If you glance at the starting line cyclocross or cross-country race, you'll most likely notice the Shimano XC902 Cycling Shoes on the riders' feet, and for good reason, too. When we get a pair of these shoes in our hands, or better yet, on our feet, we experience that world-class fit, low weight, and efficiency that the pros count on to earn a paycheck. Shimano constructs the XC902 with a one-piece, reinforced synthetic upper with numerous perforations allow the feet to breathe. Dialing in the fit comes courtesy of the dual Boa Li2 dials, offering independent and micro-adjustable tension across the top of the foot. On the rear of the shoe, Shimano uses an external cup that covers the carbon sole and the back of the heel. This design supports the heel, preventing twisting and rolling, stabilizing it for more efficiency. A gripping fabric inside the shoe further bolsters the foothold, providing a solid foundation for dishing out the big watts at the race start and on the pedaling upstroke while maintaining traction on a slippery surface.
