Seems like many people have tried twisting their foot in a strap, when crashing with high speed or just riding waves.
Besides giving a lot of comfort, the Rotatable Footstrap Plate adds also SAFETY.
A little stop feature can be removed, so the plate (and your foot) can make a full turn when your board spins.
