The Chamber II shoe holds fast to the legacy of our original EWS and DH World Cup-winning Chamber shoesecure fit, a durable water-resistant reinforced microfiber upper and a full Vibram Megagrip rubber outsoleand steps up to a new level 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 thats better from top to bottom, with the right amount of flex for uphill pushing, incredible pedaling efficiency and a better connection to the pedals.
