On May 24, , the Committee on Prosthetics Research and Development of the Prosthetics Research Board. National Academy of Sciences- National Research Council, recommended approval of the production models of the SACH* Foot for adult male amputees. Plate A shows one of these newly accepted prosthetic components whose design obviates a prosthetic-ankle joint.
Concurrent with acceptance was the release of tentative manufacturing specifications as well as finalized instructions for installation and adjustment of the SACH Foot in the prosthetics shop. A pre-shaped oversize foot is now being manufactured under control of detailed specifications. Sizing and ordering criteria, final shaping, and assembly of the SACH Foot to prostheses are described in the installation and adjustment instructions which are part of this article.
The basic functional principles of the SACH Foot are not new to the prosthetic technology. Many foot designs of similar types have existed for some time. However, concerted development and evaluation performed within the Federal Government's Artificial Limb Program between and have transformed diverse predecessors into one generally acceptable and standard manufactured design. The SACH Foot for adult male amputees**, although superficially simply in design, provides many of the foot and ankle functions required of prostheses. It is not a complex device, yet faulty construction, shaping, and prosthetic installation may very easily result, limiting function and causing early structural failure. Therefore, the Artificial Limb Program has recommended the release of tentative manufacturing specifications and precise installation and adjustment instructions. Adherence to the specifications by manufacturers and to the instructions by prosthetists will assure to all, limb dealers and patients alike, that the SACH Foot will always be the same valuable product which was carefully developed and evaluated in the Artificial Limb Program.
A. A. Marks, in , patented an artificial foot for direct attachment to a prosthetic shank; no ankle joint, was to be employed. The patent describes layers of rubber used to provide "sufficient elasticity" for toe action, particularly at toe-off. Although not specifically claimed in the patent, the heel portion of the foot had rubber of sufficient thickness to provide some degree of plantar flexion during walking. A core made from wood, or "any other suitable material" was shaped to provide, in a manner rather similar to the SACH Foot, a smooth roll-over or "rocker" action at the terminus of the stance phase.
In a patent of , G. E. and W. L. Marks describe a similar artificial foot having an internal, inelastic core, but also specifying a rubber heel portion which contained a spring "being free to yield with the rubber." Plate A - Production Model of the SACH Foot
The patentees describe the foot as having "actions when under heel or toe pressure, as during the act of walking, which greatly enhance the value of the foot and facilitate its use by and add comfort to the wearer. . . . The foot may be made of sponge rubber for softness, lightness, noiselessness, and comfort ... (to) insure the desired resiliency under heel and toe pressure."
During the years following the times of these early patents, limb-shops in the United States, as well as in Germany and Austria, have used feet of designs similar to the basic SACH Foot: an internal, rigid core or keel of proper shape and length with resilient materials provided at the heel and toe. In Canada, the design of a lightweight but durable Syme's prostheses with necessary foot-ankle function was facilitated by the use of SACH Foot principles.
J. Foort and C. W. Radcliffe of the Prosthetic Devices Research Project, Institute of Engineering Research, University of California (Berkeley) developed the first prototypes of the present version of the SACH Foot. Since the weight of a prosthetic foot is particularly critical, being located at the greatest distance from the lower extremity stump, developmental efforts were concentrated on the selection of lightweight yet durable materials. Previously, commercial feet of similar principle had been quite heavy and had exhibited structural limitations. The crepe shoe sole material successfully used by the Canadians in the Syme's foot construction was adopted to minimize weight and maximize durability. Development efforts at the University of California defined the shape and length of the wood keel and the proper shape of the foot exterior, particularly the heel cushion, a cemented sponge rubber laminate. The SACH Foot development was facilitated by the earlier work done by the UC-Berkeley project on fundamental studies of human locomotion .
Initial evaluations of the UC-Berkeley SACH Foot yielded extremely favorable amputee reactions, particularly to the shock absorption of the heel and the "smooth transition of weight from heel to toe during the stance phase." However, the testing agency*** questioned the effectiveness of the cement bonds in the heel cushion layers. A change in the specified adhesive was made by the UC-Berkeley development group. This change noticeably overcame the difficulties had with the laminate bonds. In June, , it was recommended that the SACH Foot be manufactured in small quantities so that production versions could be tested. Problems were then encountered in getting a consistently satisfactory product; these problems were noticed in the course of evaluation and were solved by the effective "feedback" of findings to the manufacturer. In the spring of production models were found to be acceptable to the testing agency resulting in a May 24, , approval by the Committee on Prosthetics Research and Development, PRB
Absence of mechanical articulation in the prosthetic foot-ankle region eliminates maintenance problems due to frictional wear, manifested by objectionable noises, joint looseness, and thus, some instability and inconsistent function. Also, design and construction defects of the "conventional" foot's rubber bumpers and their housings have often resulted in repeated limb-shop maintenance and patient inconvenience. The direct assembly of the SACH Foot to the prosthetic shank overcomes these difficulties while furnishing necessary prosthetic fool-ankle function.
The heel cushion provides, at heel contact, a shock absorption more than equivalent to the plantar flexion of a conventional ankle. As the amputee walks over bis prosthetic foot following compression of the heel cushion, the foot begins to simulate ankle dorsiflexion. The toe approaches the floor, the prosthetic shank rotates forward over the foot, and the heel cushion decompresses. Weight is gradually taken on the ball of the SACH Foot. Directly above the ball is the anterior end of the internal, rigid keel. Weight is now borne at two points, the ball of the foot and the partially compressed heel cushion. Finally, full weight is transferred to the forward end of the wood core, or keel. The length and shape of the keel are designed to provide a smooth roll-over or "rocker" action just prior to push-off. The location of this "toe-break" or roll-over line (the anterior end of the keel) is somewhat closer to the vertical center line of the prosthetic shank than is found in conventional feet with ankle joints. Since in the SACH Foot there is no ankle joint to provide dorsiflexion. it was necessary to reduce the "toe-break" distance. Nevertheless, the University of California (Berkeley) has found this reduced distance as being quite desirable, reducing energy consumption during walking, particularly up inclines.
Tentative specifications have been developed to cover the manufacture of the SACH Foot. These specifications require the feet to be preshaped oversize by a manufacturer. Since the SACH Foot is to be fitted to the amputee's shoe, it must be shaped carefully so as not to affect function adversely by limitations imposed by the shoe itself. It is necessary, for example, to be particularly scrutinizing in shaping the heel cushion, the toe section, and the arch area for proper fit within the shoe. Prosthetists will be able to purchase SACH Feet from manufacturers who have performed initial shaping in accordance with specified templates and patterns. The contours of the preshaped foot will guide the prosthetist in performing his final shaping for shoe fit. Thus, prosthetists should not. under ordinary circumstances. deviate grossly from the contouring provided by the manufacturers; material will be removed with care by following the detailed instruction (below) but, more importantly, by maintaining the proportions provided by the manufacturers.
The manufacturing specifications also detail heel cushion compression properties, as well as all-around dimensioning of the product. Tests performed by the Standards Laboratory**** are specified as checks for both structural and functional characteristics. For example, the heel cushion delamination problem noted in the early development of the present SACH Foot would be observed during routine sampling and testing of manufacturers' products. Corrective steps could be taken by the Standards Laboratory early enough to avoid generalized amputee inconvenience. Copies of the tentative specifications will soon be made available through the Office of the Executive Director, Prosthetics Research Board, National Research Council, Constitution Avenue, Washington, D. C.
Installation and Adjustment Instructions
The following instructions,***** Installation and Adjustment of the Solid Ankle Cushion Heel (SACH) Feet For Adult Male Amputees, will be made available to prosthetists in the form of reprints of this article, which may be ordered from the headquarters of OALMA, 411 Associations Bldg., Washington 6, D. C. It is important that these instructions be carefully followed by limb-fitters so that they and their patients may avoid inconvenience and difficulty.
The Solid Ankle-Cushion Heel Foot, i.e., SACH Foot, has been designed to provide shock absorption and ankle action characteristics equivalent to the normal ankle without the use of an articulated ankle joint. The action of the SACH Foot is accomplished by the use of two functional elements: a properly shaped wedge of cushioning material built into the heel, and an internal structural core or keel shaped at the ball of the foot so as to provide a rocker action. The cushion heel provides an action which not only cushions the heel impact efficiently, but also simulates normal plantar flexion very closely. This action is indicated in Fig. 1. As shown in the drawings the foot is designed to be worn without any additional covering material.
The action of the foot is very smooth and the amputee is not conscious of sudden changes in resistance as is typically experienced in a conventional foot with an articulated ankle joint which includes a soft plantar-flexion bumper and a firm dorsi-flexion stop. At heel contact the heel cushion compresses approximately 3/8" allowing the forefoot to rotate toward the floor. This action, in combination with the additional forward inclination of the shank and foot as a whole, results in normal appearance during the first part of the stance phase. During the mid-stance, or roll-over phase, the body weight is divided between the heel and ball of the foot and there is a gradual transfer of weight forward. The shape of the structural core or keel under the ball of the foot provides support and a smooth rocker action, at push-off. The distance from the ankle center forward to the toe break is shorter than in many conventional feet. This has been found desirable as one means of reducing the energy cost of walking, especially up inclines.
SACH Feet may be purchased in a rough-shaped oversize blank in three shoe-size ranges, 6-8, 8-10, and 10-12. Each size range has a common keel size, there being 1/4" difference in toe break-ankle distance between size ranges. In addition, the heel cushions are fabricated in three stiffnesses: soft, medium, and hard. The medium heel cushion will be found suitable for most applications. If, however, after trial or on the basis of experience it appears that the soft or hard heel cushion is more suitable for a particular amputee, the appropriate type should be ordered. However, in many cases where heel cushion stiffness is suspected of being the cause of poor function, the difficulty may be traced to improper installation, alignment or adjustment.
The apparent overlap in the sizes of SACH foot blanks can be used to advantage in order to compensate for differences in height between amputees.
Table 1 suggests a procedure for ordering of borderline-size foot blanks based on amputee height. Observations of this procedure will result in the keel length of the foot being more nearly compatible with the length of the prosthesis.
In ordering foot blanks, the following should be specified: (1) Size range; (2) Right or Left; (3) Heel Stiffness Desired; e.g. 8-10 R Medium.
Do not shape the ankle portion of the foot above the shoe level until after final installation of the foot on the shank with proper toe out. Leave the ankle area rough shaped for walking trials. Fig. 2.
The shaping of the SACH Foot is very important since both its function and appearance are influenced by its shape. There are three areas, as indicated in Fig. 3, where particular care is required; these are:
The general foot contours necessary for the proper functional shaping have been preshaped into the oversize foot blank. Only minor changes in contour as necessary to reduce oversize dimensions are required. In particular no change should be made in the lower third of the posterior heel contour since this contour has been preshaped so as to provide the proper distance from heel to a line through the attachment bolt.
When inserting the foot into the shoe during fitting, always use a thin sock on the foot. Contouring the foot, as described below, can best be accomplished by sanding parallel to the laminations, using a cone or drum sander with a spindle speed of at least rpm.
The heel of the SACH Foot must be shaped so as to fit the shoe in both the relaxed and compressed conditions. The heel is shaped so as to fit the shoe tightly near the sole of the heel yet with considerable clearance near the brim of the heel counter. Approximately clearance should be allowed at the brim of the counter between the posterior, medial, and lateral surfaces of the heel of the foot and the heel counter of the shoe. This clearance should decrease gradually and extend downward approximately two-thirds of the depth of the heel counter of the shoe. The lower third of the heel of the SACH Foot is fitted snugly into the heel counter of the shoe. The clearance near the brim of the shoe allows the heel cushion to expand as it compresses under load without interference between the shoe and foot. This clearance is also extremely important in preventing wear of hose.
In shaping the heel the point of the heel should be displaced approximately to the lateral side with the foot oriented straight ahead. As the toe of the foot is rotated laterally to give the proper toe out, the point of the heel will rotate back toward the mid-line and the point of initial heel contact will again be through the geometric center of the foot. If this is not done, weight will be transferred through the lateral side of the heel cushion at the time of heel contact.
The bottom surface of the arch of the foot must be shaped to provide a minimum of 1/8" clearance between the foot and the inner sole of the shoe. If clearance is not provided, the arch of the foot will contact the sole of the shoe as the heel compresses, resulting in restriction of motion, shoe damage, and wear of hose in this area.
The upper surface of the arch of the foot is shaped so as to hold the heel cushion against the counter of the shoe and to match the shoe-lacing gap on the natural side. The toe-break of the forefoot must be shaped so as to provide a looser fit than is typical with wooden feet. The flexible material of the forefoot expands with compression as the toe bends and this expansion must be allowed for in shaping the foot. Failure to provide sufficient clearance will restrict the toe motion and cause shoe damage.
The SACH Foot is attached to a conventional wooden shank by means of a 3/8" steel carriage bolt. During manufacture the carriage bolt is inverted and its head is embedded firmly into the lower surface of the hardwood keel. A solid section of wood in the end of the shank between 1 1/2" and 2" in depth is required for installation.
Due to the soft nature of the materials used in the construction of the SACH Foot, an allowance for extra shank length is necessary in order to compensate for the compression of the foot under load. The average amputee requires an increase in length of 1/4" for this purpose. Amputees weighing less than approximately 140 lbs., or where the hard heel cushion is used, may not require the full one-quarter inch.
After adjustment of toe out and walking trials, the foot is glued in position.
The step-by-step procedure for installation of a SACH Foot as a replacement for a conventional foot on a wooden shank is as follows:
Note: While gluing alone may be adequate, it is recommended that for maximum security the foot be both glued and doweled. The procedures for doweling are:
Place reference marks on shank and top of foot to indicate the toe-out alignment for later assembly. Remove SACH Foot from shank. Drill 1/4" holes 1/2" deep into exposed surface of the wood keel anterior and posterior to the attachment bolt and parallel to it. Cut two lengths of 1" doweling 1 1/4" long. Trim one end of each piece to a point. Glue the dowels into the holes pointed end up. Place shank on attachment bolt and sighting to see that the alignment marks are in line, press down firmly until the sharpened dowels make an impression in the bottom of the shank. Using these marks as centers, drill holes 1" deep into the shank, perpendicular to the cut section. Apply glue to the protruding dowels, top of the foot and bottom of the shank and press together firmly. Install lock washer and attachment nut on the attachment bolt. Tighten securely. Use "Woodlock" or similar water resistant adhesive.
There are two types of adjustment possible with the SACH Foot: (1) change in heel cushion stiffness and (2) change in heel cushion thickness.
The heel elevation of the foot sometimes requires adjustment due to differences in shoe lasts. The SACH Foot is presently manufactured with an 11/16" heel elevation, i.e., the bottom of the heel is 11/16" above the level of the ball of the foot with the attachment surface parallel to the floor. Before any adjustment of heel elevation is attempted, it is important to recheck the clearance between the arch of the foot and the shoe (Section III, Shaping). The wedge angle of the heel cushion should not be changed.
An increase in heel elevation (decrease in heel cushion thickness) is indicated if there is excessive heel cushion compression when the amputee stands on the prosthesis with the top of the foot parallel to the floor. A limitation in plantar flexion in walking and/or a decrease in knee stability in both walking and standing may accompany this condition. The heel elevation may be increased up to 3/16" by sanding foam crepe sole material from the bottom of the heel. If an increase in heel elevation greater than 3/16" is indicated, improper sawing of the shank should be suspected. This should be corrected at the junction of the shank and foot by rechecking alignment; and resawing, sanding or wedging as necessary.
A decrease in heel elevation (increase in heel cushion thickness) is indicated where there is insufficient or no compression of the heel cushion in the standing position. This condition will be reflected in gait by excessive knee stability and a feeling of "walking over a hill." The condition is corrected by cementing shims of crepe sole material, leather or other firm flexible material to the bottom of the heel area using Stabond T-161 or equivalent until the desired heel cushion compression is achieved.
A change in heel cushion stiffness is indicated where a check of heel cushion compression in the standing position shows proper adjustment of heel elevation, yet observations indicate too soft or too hard an action while walking.
The step-by-step procedure for exchange of heel cushion in the SACH Foot is as follows:

Choosing the best prosthetic foot is a personal journey. A prosthetic foot replaces a missing foot, helping you walk and move.
The ideal choice depends on your daily activities, mobility, and personal goals. This guide will help you understand what to consider, the types available, and how to make the best choice for your lifestyle.
Prosthetic feet are more than just a functional replacement for a lost human foot. They are a key to unlocking new potentials, reaching new heights, and conquering new challenges.
Choosing a prosthetic foot isn’t just about walking again. It’s about living the way you want to. That choice depends on your body, your routine, and what feels right for you.
The level of amputation is a significant factor that directly influences the type of prosthetic foot that would best serve your needs.
If you’ve had a partial foot amputation like losing your toes or the front of your foot, you’ll need support that matches your remaining structure.
If you’ve had a below-knee amputation, your natural knee joint is intact. In this case, your prosthetist will look at factors like the length of your residual limb, its strength and range of motion to recommend a suitable foot.
For above-knee amputations, a prosthetic knee joint is necessary and its type will help you choose the suitable prosthetic foot.
Your prosthetist will assess how the knee joint functions and then suggest a foot that complements it.
How active are you? Do you enjoy a morning jog or prefer a leisurely stroll in the park? Your response to these questions influences the decision-making process for the right prosthetic foot.
Prosthetic feet are built to match how much you move. For lower activity levels like walking indoors or on flat ground, the goal is to keep you stable and balanced. So simpler feet like a single-axis model may be enough.
If you’re more active, your foot should absorb shock at heel strike, adapt to uneven ground, roll smoothly from heel to toe, and help push you forward as you step. A multiaxial or energy-storing foot could give you the flexibility and bounce you need.
Materials also change depending on how active you are. Prosthetic feet made with wood, foam, or plastic usually offer more stability like an anatomical foot and work well for lower activity levels.
If you’re more active, carbon fiber prosthetics is common and ideal. It’s lighter and built to absorb shock and return energy with each step.
Some prosthetic feet have a spring in the heel and forefoot, making them ideal for walking at different speeds, running, or climbing stairs with confidence.
The longer the carbon fiber spring, the more energy it stores, making the foot even more responsive.
Selection of a prosthetic foot is more than just a medical decision – it’s a lifestyle choice. Age, weight, foot size, and lifestyle—all of this matters.
These factors help determine the level of durability and functionality required for your daily activities and overall quality of life.

A teenager and a retiree will have different needs, even with the same amputation level. So it helps to look at your habits and goals before choosing.
Ask yourself:
These questions might help you select the prosthetic foot that will complement and function well in your unique circumstances.
When selecting a prosthetic foot, consider these factors:
You don’t have to figure it out alone. A prosthetist can help you test different options and explain how they work. Just remember, your foot, your life. Make sure it fits both.
Understanding the different types of prosthetic feet can help you choose the right one for your needs.
The SACH foot is a basic and non-moving prosthetic foot with a cushioned heel that helps absorb shock during walking.
It provides single-axis motion that mimics the natural movement of your foot, making it ideal if you have lower activity levels who prioritize stability and support.
One standout option is the Ottobock SACH+ Foot, designed especially for seniors or those with low mobility.
Instead of the traditional wooden core, the SACH+ Foot uses a fiberglass-reinforced plastic core combined with durable functional foam.
This makes it stronger, more water-resistant, and better for everyday use. It also gives you a stable and safe step when your heel touches the ground.
It comes in both standard and narrow foot shapes, with natural-looking toes and a smooth surface that blends in during daily activities.
Your prosthetist can help match the right model to your foot size and body weight, ensuring comfort and confidence with every step.
A Single-Axis foot moves up and down to improve stability, especially on slopes or uneven ground. It helps enhance knee stability, making it a good option if you have knee or hip challenges.
Though it may need more maintenance due to moving parts, the added control can be worth it.
WillowWood offers one of the most advanced designs in this category. Their Single Axis Foot is made from strong and lightweight composites, making it up to 20% lighter than traditional versions.
It includes a molded-in titanium pyramid, a water-resistant unisex foot shell, and interchangeable bumpers with different resistance levels.
You can get it as a standalone foot or as part of a full assembly with the ankle and bumpers included.
A multi-axial foot moves in different directions, making it easier to walk on uneven ground. It helps absorb impact and reduces stress on your residual limb, which is great if you’re active and need more balance and comfort.
The Triton Side Flex by Ottobock is a strong example of this design. It’s made for highly active users who move between different indoor and outdoor surfaces and want reliable response and control, even during high-impact movements.
This foot offers side-to-side flexibility and solid ground contact, helping you stay steady on slopes or rough terrain.
By reducing the strain on your knee and socket, it lets you move more naturally and focus on your day—not your steps.
It gives you smooth rollover, high energy return, and the support to stay agile in motion.
For many, it's more than a foot—it's the base that brings freedom back.
This type of foot stores and releases energy as you walk, helping you move with a more natural and efficient stride.
They’re often made with lightweight, durable carbon fiber that absorbs energy when your foot presses down and releases it during push-off.
Great for those with moderate to high activity levels as it offers more flexibility and support for different walking speeds and terrains.
The Fillauer Ibex XD is a great example. It uses micro-slice technology in the pylon and a split heel plate to control side-to-side motion on uneven ground.
Its long carbon pylon and full-length heel plate help it reach foot-flat faster, storing more energy without sacrificing stability.
From heel strike to toe-off, every part of the foot works together to give you both balance and power. An adjustable heel wedge also lets you fine-tune the stiffness to match your comfort and activity needs.
It’s a tough and high-performing option for heavier users who need solid energy return and the confidence to keep moving..
Microprocessor feet use built-in sensors to adjust the ankle’s position in real time, based on how fast you're walking and the surface you're on.
They help you move more smoothly across ramps, stairs, and uneven ground by offering a personalized walking experience.
While they need charging and tend to be more expensive, the stability and comfort they offer make a big difference—especially for active users.
The Össur Proprio Foot is a great example of this technology. It’s built for low to moderately active users and focuses on safety by raising the toe during swing phase, reducing the chance of tripping.
It automatically adapts to changes in terrain like slopes and stairs, making each step more stable.
The dynamic carbon foot blade gives it a smooth roll-over, while special modes make sitting and standing more comfortable.
It’s waterproof in both salt and fresh water and comes with an app that helps with setup, tracking steps, adjusting ankle position, and checking the battery.
Proprio Foot gives you the freedom to move more naturally, with more confidence in every step.
Battery-powered prosthetic feet help mimic the movement of your natural foot and ankle. They provide extra push at toe-off, reduce joint strain, and make walking more comfortable and stable.
While they offer great benefits like improved walking, they do come with some challenges, such as added weight, maintenance, and the need for regular charging.
The Ottobock Empower prosthetic foot is made for active users who move between indoor and outdoor spaces. It’s perfect if you walk longer distances and at higher speeds.
It helps mimic muscle function by providing powered push-off and extra comfort during rollover, especially on slopes.
The battery lasts up to eight hours, depending on how much you use it, and can be charged in under 90 minutes with a dual charger. The battery level is easy to monitor, so you’re always in control.
If you want both mobility and durability, the Empower foot is more than just a prosthetic—it's a foundation for an active lifestyle.
Hydraulic prosthetic feet adjust resistance based on your movements, offering better stability and comfort on surfaces like ramps and stairs. They’re ideal if you have higher mobility needs, especially if you're active.
The Blatchford Echelon is a great example. It has a waterproof hydraulic ankle that absorbs impact, adjusts to rough surfaces, and stays flexed at toe-off.
This design reduces pressure on the prosthetic socket and joints, improving comfort, posture, and lowering the risk of falls.
Tailored for specific activities like running, swimming, or hiking, these feet enhance performance for particular sports or hobbies, offering specialized support for various motions and environments.
The Össur Flex-Foot Cheetah is a high-performance carbon fiber foot designed for sprinting, trusted by athletes since .
It delivers excellent energy return with performance adjusted to your weight and impact, ideal for long distance runners. It is also waterproof, offering protection in fresh, salt, and chlorinated water.
Your activity level plays a major role in choosing the right prosthetic foot.
To guide this process, mobility levels are classified by K Levels:
K-Levels are used to indicate rehabilitation potential and assess how effectively you can use a prosthetic device.
Understanding your K-Level helps determine which prosthetic foot fits your lifestyle and needs.
When selecting a prosthetic foot, consider discussing:
When selecting a prosthetic foot, it’s important to discuss these things to ensure you get the best fit and comfort for your lifestyle.
Your prosthetist can guide you through the process, helping you choose the right foot, make necessary adjustments, and test different options during trial periods.
Additionally, understanding your insurance coverage and any costs will help you make informed decisions about your prosthetic care.
A prosthesis can cost anywhere between $3,000 and more than $100,000, depending on the extent of the prosthetic. Be sure to check with your insurance company before making any decisions.
The most common prosthetic foot is the SACH foot, which is basic, low-cost, and includes a solid ankle and rigid keel. Consider this option for a simple and affordable prosthetic foot.
Typically, prosthetic foot lasts 3-5 years, but this varies based on usage and care.
It's generally not recommended to use one prosthetic foot for all activities, as activities require different levels of support. Your prosthetist will help you select the best foot based on your needs and activity level.
