Invisa-Lite Shin Guards are designed for maximum protection and minimal bulk. Using a dual density impact foam, we put a denser, harder durometer 3D foam on the outside to stop pedal stabs and added an inner softer layer on the inside for comfort. Constructed with high quality and innovative materials, offering a compression fit with a bonded silicone ring to insure that they will stay in place for the whole session, never feel the pain of pedals again.
