  • Product Description

    The Shimano R321 SPD-SL road racing shoes are performance wear for winners. Increasing pedalling efficiency is a super stiff sole with uni-directional fibres to keep things rigid, whilst keeping weight to a minimum. 

    An aerodynamic wrap-around upper design reduces drag by up to 5.5% for the marginal gains you need to stand on the podium. 

    Shimano's R321 SPD-SL shoes offer pro let fit thanks to the Custom-Fit upper and insole. These mouldable areas conform to your foot anatomy for an optimised fit that is very comfortable. 

    The Dynalast sole also offers an extra 11mm of cleat adjustment for the best shoe to pedal fit.
