Transfemoral and knee disarticulation Transformed

We’ve re-invented sockets from the ground up. No more static socket shape. No more hard ischial seat. No more loss of suction. The Socket-less Socket™ truly conforms to the user, providing a custom-fit socket every time you put it on.

Limit-less Configurations

The above knee Socket-less Socket™ is now available in 3 configuration options – SwingBrim™, cX-Hybrid™, and cX™. Connect with us for a free consultation on which socket configuration is right for you.

The Biggest Advancement in Sockets, since the Socket-less Socket™.

In our continued evolution of great socket designs, we’ve improved the best socket design around. The new configuration X™ offers twice the control and stability of the original Socket-less Socket™, and is even simpler to fit.

As conforming as a hammock.

Our patent pending SwingBrim™ technology perfectly conforms to the user just like a hammock, providing a soft floating cushioned seat on every step. It’s the difference between sitting on a hard chair versus into a soft hammock.

Ridiculously light.

Now 40% lighter than the original Socket-less Socket™. Our NASA-inspired lightweight design and materials are only a fraction of what conventional sockets weigh - with a typical weight reduction of over 2 pounds. You’ll be amazed at how light a socket can feel.

Solid as a rock.

Exceptional stability and limb control, yet conforming and comfortable. The floating Femoral Lock Pad dynamically captures the limb to provide a socket that feels like a part of you.

Micro-adjustable comfort, every morning.

Conventional prosthetics are static in shape, and require frequent fitting adjustments to match the ever-changing human body. Our technology fits differently. We enable you to micro-adjust for a comfortable fit every time you put your prosthesis on. If you’re the kind of person who wants full control of how your socket fits, this technology is for you.


A paradigm shift in how prosthetics are fit.

Socket-Soft™ converts simple limb measurements to a pre-fit socket, making the fitting process faster and more efficient. The practitioner simply micro-adjusts the pre-fit socket on the user for a perfect customized fit. Launch Socket-Soft™ to explore the full Socket-less Socket™ training.


Donning and Doffing.

Donning as easy and comfortable as putting on your favorite pair of tennis shoes.


Smooth like Butter.

The compliant fabric-based socket cushions your step. Walking has never felt so smooth.

The SwingBrim™ socket configuration offers the same dynamic brim comfort as the full Socket-less Socket™ cX™, but can be retro-fit into most conventional AK sockets through simple trim line modifications.   Its the difference between sitting on a hard chair versus into a soft hammock.

The end of rigid brims.

The new SwingBrim™ technology replaces existing rigid brims with a dynamic brim shape that eliminates point specific ischial loading.

Comfortable as a brim should be.

The human body is dynamic - the socket should also be dynamic. The SwingBrim™ hammock-fit technology conforms to the body, instead of the body having to conform to a static brim.

No more hump in sitting.

Traditional sockets are rigid and result in the user sitting on a bulky hump of plastic. The SwingBrim™ is so thin and flexible you likely wont notice its there.

Take control of your brim comfort.

The SwingBrim™ support is adjustable for daily comfort. We understand that your body changes - now your brim can too.
