The Shimano S-PHYRE SH-TR903 sets a high standard for comfort, power transfer, and transition speed. Built for sprint and Olympic distance triathlon races, it features a single wide closure strap designed to minimize time in T1 when speed is critical.
As the first multi-sport shoe with the S-PHYRE designation, it features a water-resistant synthetic microfiber upper with mesh panels and variable perforations for quick drying. A stiff carbon sole with a low stack height places the foot closer to the axle, while a heel stabilizer holds the foot in an optimal power position.
