The top model of Shimano's S-Phyre line is an uncompromising racing shoe, custom-made for you as a road cyclist. The 360° enveloping, one-piece construction sets new standards in fit, pedaling stability, stiffness, and weight reduction. The shoe conforms to your foot, not the other way around. Reinforced and flexible mesh fabric is integrated into the front side area, allowing for a perfect fit. The external heel cup stabilizes the foot during explosive movements such as sprints or high cadences.
