Hpr green

Brooks’ proprietary HPR (High Performance Rubber) Green outsole — featured in our Beast®, Ariel®, Addiction™ Walker, Addiction™ Walker V-Strap, and our entire Trail footwear collection — is a durable, long-wearing outsole compound made from sand rather than oil. That warrants a high-five from Mother Nature for petroleum reduction. This environmentally friendlier composition also results in premium wet-dry traction for excellent skid-resistance.
