Built for tough off-road conditions, the Shimano XC903 S-PHYRE Cycling Shoe is the perfect companion for our cross-country or cyclocross adventures. Built with a lightweight microfiber synthetic leather and mesh upper with a carbon fiber composite midsole, we are provided with exceptional stability and power transfer without sacrificing breathability. For a secure, personalized fit, we twist the dual BOA® Li2 dials to tighten down the low-profile crossover lacing across the foot, and the ULTREAD rubber outsole provides us with trustworthy grip when hike-a-bike sections cross our path.
