S-PHYRE SH-TR903

Product Information

The Shimano S-PHYRE SH-TR903 triathlon cycling shoes are engineered to provide triathletes with a significant edge in transitions and on the bike course. As the first multi-sport cycling shoe to earn Shimano's top-tier S-PHYRE designation, these shoes prioritize speed, power transfer, and comfort for optimal race performance. They're designed to handle the demands of sprint and Olympic distance races, but are a solid choice for any triathlete seeking marginal gains.

With a focus on lightning-fast transitions, the TR903 incorporates a race-tuned closure system and quick-drying materials. The stiff carbon sole ensures efficient power delivery, while thoughtful ventilation and water drainage keep your feet comfortable, even when riding sockless.
