These men's Five Ten mountain bike shoes keep you comfortable and protected while you ride. The canvas upper is durable and flexible, and the tread helps your feet stay securely planted on the pedals. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic - reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
