For elite cross-country racers who need class-leading stiffness, superior fit, premium materials and light weight, the SCOTT MTB RC shoe is the only choice. This shoe offers a dual-zone Boa� IP1 lacing system that delivers ultimate comfort and response, allowing on-the-fly adjustability in two separate portions. We placed an upper Boa� IP1 closure at the top of the shoe and a midfoot IP1 reel with power zone guides to allow 2:1 pull across the forefoot. It features an asymmetric microfiber airmesh conforming upper with a new adaptive fit pattern. The ErgoLogic insole features an adjustable arch support and metatarsal button. The stiff Carbon fiber outsole has a stiffness index of 10.
