Below, you will find brief descriptions and links to more detailed articles on all the bionic feet/ankles currently on the market.
Freedom Innovation’s Kinnex is one of the most advanced bionic foot/ankle devices on the market. With a 30-degree range of motion, 3 sensors, and a sophisticated microprocessor, Kinnex automatically adjusts to changing terrain on each step.
Fillauer’s Raize Foot is a lightweight, low-profile bionic foot/ankle. Its microprocessor actively manages flexion resistance for a smoother rollover during the Stance Phase of the gait cycle. It also allows users to adjust heel height to accommodate different shoes.
Blatchford’s Elan Foot is another worthy competitor in the bionic foot/ankle market. Its ability to automatically adjust both dorsiflexion and plantarflexion resistance on each step produces a smooth gait on many different types of terrain, including ramps, slopes, and stairs.
