Completely redesigned to handle the demands of cross-country racing and downcountry riding, the Five Ten Kestrel BOA Mountain Bike Shoe is built for speed and comfort. Made with recycled materials, the abrasion-resistant upper is hyper-breathable and features two hook-and-loop straps and a BOA closure so that we can dial in our ideal fit for high-output rides. A full-length glass fiber-reinforced plate allows us to really put the hammer down on the climbs and is bolstered by Stealth Marathon rubber lugs for insane amounts of traction off the bike.
