S-PHYRE SH-RC903 PWR

• Intended use: S-PHYRE performance shoe aimed at sprinting, track competition and time trials; listed by Shimano USA in Road.
• Sole and performance: Very stiff carbon sole and a low-profile midsole promote stable, efficient pedaling.
• Upper: Reinforced wraparound construction with a tongue supports the foot. Differently sized perforations add airflow and flexibility.
• Closure: A metal BOA Li2 dial works with a power-boost cable guide and a hook-and-loop toe strap to limit movement inside the shoe.

• Finish: An optical coating gives the sole and heel a color-shifting crystal appearance.
