Prosthetic Feet - An Overview

Updated: Dec 30, 2020


There are several types of feet available that your Prosthetist will consider when creating your Prosthesis. The type of foot will depend on your activity level, occupation, weight, hobbies, and the source of funding.


SACH - S-A-C-H stands for solid ankle cushioned heel. These feet have no hinged parts therefore they tend to be much lower in cost, very durable, and virtually maintenance free. They are typically chosen for their durability and low weight.


Multi-axial - They are similar in weight, durability, & cost to the single-axis foot, only these feet also move side to side, which is ideal for uneven terrain. These feet are better suited for a more active lifestyle.

Microprocessor - They are computerized and allow for a more adaptive response to speed and terrain conditions. They work with hydraulics and sensors to react in real time to the change of pace, incline of slope, and what type of surface the user is walking on. These tend to be more costly and heavier than a more traditional foot. Since they contain so much technology they are more delicate and should avoid dusty and wet conditions. This sort of a foot typically suggests a more active lifestyle.

Dynamic Response - Also known as “energy storing feet”, they use the same method as a diving board, releasing stored energy as the users walk. They provide a normal range of motion and a more symmetric gait. The spring effect is only noticeable to the user but it reduces the energy required, allowing the user to walk further. These are for moderate to very active individuals.


Special Use - There are many specialty feet out there, we’ll limit this list to just a few common types of specialty feet.

  • Adjustable Heel foot is an option for those who wear heels, with up to a 2” heel safety. Most prosthetic feet limit you to wearing only flat shoes. Something similar was used for a Dancing with the Stars contestant.

  • Running Blade or “cheetah” running prosthesis, just because you want to run doesn’t mean you need a running blade; but for some runners it would make more sense to have something specific, especially for long distance runners.
