These men's Five Ten mountain bike shoes deliver superior pedal traction with the durability and comfort of a canvas upper. The Stealth rubber outsole provides unbeatable grip and versatility. 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.
