PROPRIO FOOT®

Because the world isn't flat.

Because the world is not flat and full of opportunities, Proprio Foot is designed to improve the safety of low to moderately active users, by increasing toe clearance in swing phase and adapting to changing terrain.

Its adjustable heel height allows changing shoes easily at anytime and it is fully waterproof in salt and fresh water to enjoy a range of water activities.*

Frequently Asked Questions

How is Proprio Foot different than a traditional mechanical prosthetic foot?

Proprio Foot uses a powered ankle unit to provide increased range of motion, active toe-lift, and pre-positioning in addition to the benefits of our Pro-Flex carbon foot technology. All of these features were designed to allow you to walk more naturally.

Is Proprio Foot right for me?

Clinically, Proprio Foot is for people with unilateral or bilateral amputations above or below the knee. The best way to understand the benefits of Proprio Foot is to discuss it with your prosthetist and try it for yourself!

How can I get a Proprio Foot?
