Like the standard version, Shimano’s XC903 S-PHYRE Wide Cycling Shoe brings exceptional off-road comfort and performance to our cross-country or cyclocross efforts, but with some extra room inside. The combination of the microfiber synthetic leather/mesh upper and carbon fiber composite midsole provides us with the breathability, stability, and power transfer needed to ride at our best, while the dual BOA® Li2 dials aid us in finding the perfect fit across the entire foot. When walking in unrideable sections, the ULTREAD rubber outsole and technical tread pattern provide us with exceptional traction.
