Brake in style with Impala roller skate stoppers. These roller skate stoppers are made from long-wearing polyurethane and allow "grab free" braking (so you can come to a stop with style). Stoppers can also be used to safely step your way up, down and around steps, slopes, and gravel. These Impala Stoppers are perfect for recreational skating in the streets, the skatepark, by the beach and at the rink. Each pack comes with two PU stoppers and includes a set of bolts to fasten your new skate accessory in place.
