As soon as I put the socket on and started walking, I could feel the socket adjusting to my leg. It is such a relief to know that my prosthesis is going to fit perfectly all day without me even having to think about it.

Why fit matters

The sock routine, retired

As your limb size fluctuates through the day, traditional sockets become loose or too tight — leading to discomfort, skin irritation, and shorter wear time. Many amputees manage this by adding and removing prosthetic socks, over and over. Kinn™ replaces that routine with a socket that takes up volume change on its own, holding the tension you and your prosthetist chose.
