Choose between the GORE Bike Wear regular and thermo Race Power II Shoe Covers. Or just get both pairs. The Gore-Tex Performance Shell blocks moisture without sealing your shoe and foot in air-tight stuffiness, while abrasion-resistant material at the sole increases this shoe cover 1/2s durability. Cut-outs accommodate both your pedal system and the heel of your shoe, while an adjustable hook-and-loop system and neoprene stretch shaft top provide a snug, aerodynamic fit. The thermo shoe cover has a warm fleece backing for chilly races.
