The Giro Men's Chamber II Mountain Bike Shoes are made with a durable water-resistant reinforced microfiber upper and a full Vibram Megagrip rubber outsole with a 10mm cleat setback. More setback allows you to position the pedals further back under the arch of the foot to reduce fatigue and enhance positioning for technical terrain. The internal shank also has been updated with a Tri-Mold construction that optimizes stiffness and flex for each zone of the foot. The result is a new level of performance that's better from top to bottom, with the right amount of flex for uphill pushing, incredible pedaling efficiency, and a better connection to the pedals. | Giro Men's Chamber II Bike Shoes
