Why We Like The Shimano RC903 S-PHYRE Cycling Shoe

Built specifically for road racing, the high-performance Shimano RC903 S-PHYRE Cycling Shoes are engineered to get you to the finish line with unmatched speed, power, and efficiency. The upper of the shoe is wrapped in 360º reinforced micro-fiber leather with perforated venting, allowing for excellent breathability, and is secured with dual BOA Li2 dials for quick adjustments, minimal pressure points, and a snug fit to your foot. DYNALAST technology reduces fatigue on longer rides by keeping your foot securely in place, while an anti-twist heel cup adds stability to the heel as you apply max power to the pedals during a breakaway or field sprint.
