This is a replacement protective rubber front bumper for your quad roller skates. This bumper fits all models of ParkStar, Quadstar, and Prostar boots and comes as a set of two bumpers (left and right).  

Use a hairdryer to make the rubber warm. Slowly peel off the old rubber bumper. You may need to reheat the rubber multiple times to get the whole of the bumper off. Use Loctite 401 or similar to then attach the new bumper to the boot.
