Prosthetic engineering for a life in motion.


Prosthetic sockets are stuck in the age of Dutch wooden shoes.
Ours Aren't.

Stumpworx approaches prosthetic design through a new lens.

Drawing from decades of material advancements in athletic footwear and performance apparel, we are creating a custom prosthetic ecosystem using performance textiles and modern manufacturing processes.


Amputee-Driven Innovation

We prototype and produce prosthetic limbs and harnesses through a custom, remote fabrication process. 

Starting with a digital scan of the limb, we create a lightweight 3D printed frame. This joins to a shoe-like socket that is laminated and sewn.
The result is a prosthesis that won't hold you back.
