We’ve seen plenty of shoes that put a spring in your step, but the BIUS1 is designed to put a spring in your pedal stroke. This bicycle pedal does so by actually including a spring-mounting with it, which is designed to reduce the stress on the joints. BioConform devised these pedals so that the shoe stays in place against the platform, but the pedal can move in and out along the axle so the leg does its own thing. The company even claims these pedals work a wider range of leg muscles than other pedals.
