OUTSIDER Foot by Hopper, The Everyday Solution
Description
The Outsider foot is a super-lightweight system that offers the best of both worlds, combining fluid walking and dynamic running without compromise.
- Lightness
The lightest foot in its category, enabled by high-performance components including InfiniFoam technology, titanium, and an aerospace-grade carbon composite structure.
- Fluid Motion
A natural heel-to-toe rollover that enhances comfort and delivers a smoother walking experience supported by continuous SALOMON InfiniFoam pad from heel to toe.
- Dynamism
Inspired by our blades, the Outsider foot delivers high energy return to support dynamic and efficient movement, both in everyday life and during more intense activities. It’s combines the durability and flexibility of fiberglass composite with the responsiveness of carbon fiber through a specific resin system provided by AIRBUS up-cycled composites.

The Outsider foot bridges the gap between everyday prosthetic feet and sport-specific devices, reducing the need for multiple setups while maintaining lightweight construction and clinical reliability alongside with a unique sporty design.
Engineered in aerospace-grade carbon composite from Airbus, inspired by the Hopper running blades, the split blade of the foot delivers smooth rollover and controlled, high energy return to support walking, variable cadence, and higher-impact activities within a single device.
The foot is paired with a uniquely designed foot shell made from InfiniFoam, an innovative material technology developed by Salomon. This material is designed to ensure a fluid and continuous motion from the heel to the toe and a perfect fit in any shoes. Components can be easily replaced thanks to an easy-to-use hook-and-loop fastener attachment system.
Let’s put movement to the heart of everyday lives!
