Runaway HX (RS2-K1)

Runaway HX (RS2-K1)

by Freedom

Amputees greatly value the versatility offered by the Runway adjustable heel height prosthetic foot. Its anatomical gliding ankle maintains appropriate foot alignment to provide knee stability and consistent performance at all heel heights. Users can adjust from a flat heel for sandals or walking barefoot at home, up to a 2 inch heel for dress shoes and even cowboy boots. The Runway is the only heel height adjustable product manufactured using carbon fiber, which stores and returns energy so that users can walk farther, faster, longer. Unlike competitive products, the Runway incorporates carbon fiber layers that are tailored to an individual’s body weight and impact level, providing a customized product for superior comfort. Rated to 255lbs., the Runway offers the highest user weight rating in the heel height adjustable product category, making it accessible to more amputees.

Originally launched with a push button adjustment mechanism with ten height settings, the new Runway HX allows users to make precise adjustments within the 0-2″ range. A port in the posterior (rear) aspect of the foot shell provides access to adjust the ankle by simply turning a 4mm hex key to reach the desired position. In addition to the ability to make easy and precise adjustments, the Runway HX also offers tighter tolerances for improved durability.

Both the push button Runway and the Runway HX are available with an optional sandal toe foot shell, which has been redesigned to appear more natural and is capable of pleasing even the most discerning users


  • As the only user-adjustable heel height foot designed for active K3 amputees, the device is customized to user weight and activity level to provide superior comfort and energy return
