How to select the right prosthetic foot

Please note: Choosing a prosthetic foot that best suits your personal requirements, needs and goals is a complex task. Your O&P professional is an expert in this field. Thanks to his education, experience and biomechanical knowledge, he will choose the prosthetic foot that helps achieve the best possible fitting outcome for you individually. The information provided in this section only serve as a guidance. Please contact your O&P professional if you have more detailed questions.

Personal factors

Apart from all the technical selection criteria, your O&P professional will keep in mind your personal needs, living situation and goals when choosing the foot prosthesis. These factors might be the desire to participate in sports activities or the ability to paint your toenails. These are of great importance because your prosthetic foot should be like an extension of yourself.

Amputation level

Your amputation level will be one of the first things that needs to be looked at when chosing the components in your prosthesis. An above knee amputation requires a prosthetic knee joint and the type of knee joint will help to define the appropriate prosthetic foot. This is where your O&P professional will assess the functions of the prosthetic knee joint and recommend an appropriate prosthetic foot. Because the natural knee joint is intact after a below knee amputation, your O&P professional will consider factors like length of the residual limb, strength and range of motion when recommending an appropriate foot prosthesis.


Activity level

Manufacturers categorize prosthetic feet by the user’s activity level – also called mobility grade. This means that not every prosthetic foot can be used by every user. Selecting a prosthesis that matches your activity level will maximize your mobility and your quality of life. Here are some very basic indications for identifying your activity level. If you are on the border between two activity levels, your O&P professional will consider multiple products to assess the one that is best for you.
