Xtreme

Xtreme is a pair of custom 3D-printed insoles for competitive cyclists.
They are obtained by the 3D scan of the cyclist’s feet and the foot pressure test during the cycle gait. Totally customized insoles in terms of shape and material softness are developed to reduce peak pressures, enhance comfort and prevent injuries.
