This shoe cover is as committed as you are to riding through the wettest weather, thanks to three-layer waterproof/breathable fabric that blocks wind and stops rain in its tracks. The WRX Shoe cover works with both road and mountain bike shoes and can be used with standard footwear as well. (We suggest sizing up for flat pedal and street shoes). A two-stage hook and loop closure makes it easy to pull these on and keeps the elements at bay. BioViz reflective elements on the toe, side, and heel increase low-light visibility.
