The Shimano SH-XC61 is one seriously tough mountain bike shoe that can take a beating and keep churning out power to the pedals. Synthetic leather uppers provide great protection and excellent durability from cuts and abrasions. The stiff carbon sole, reinforced with mud shedding polyurethane lugs, offers efficient power transfer 'on' the bike and awesome traction 'off' the bike. Oversized micro-adjustable buckle and dual offset straps combine with an anatomically curved last for a comfortable and natural fit. 632 grams/pair.
