A residual limb swells and shrinks with activity, heat, hydration, and time on your feet. A rigid socket fit at 9 a.m. can be loose by noon and painful by evening — which is why so many amputees carry a bag of socks.
Figures reported by Vessl Prosthetics from published clinician and amputee surveys.
Kinn™ harvests the energy of each step to power its own adjustments — a fully mechanical system that holds the socket tension you and your prosthetist choose.

Automatic socket adjustments hold a secure fit tailored to your limb as it changes — hour by hour.
No more juggling sock plies through the day. Don the socket once and get on with your life.
Improved rotational stability and shock absorption gives you the freedom to move through your daily life, easily transitioning from sitting to running and more.
