The XC903 S-PHYRE combines a carbon sole with Ultread XC rubber tread for clipless mountain-bike riding. BOA Li2 adjustment, perforated upper panels and heel-cuff stabilization form the fit system around the foot.
This white pair is the wide version in size 41. Choose using Shimano’s wide-version sizing rather than assuming the standard fit is equivalent. The two-bolt sole needs cleats suited to the pedal system; rubber tread is part of the outsole, not a substitute for the cleat interface.
