A shoe cover ideal for cold and wet days. From the best-selling H2O shoe cover, a new highly elastic model without a rear zipper has been developed to enhance comfort and water resistance. It is easy to put on: simply slip it over the shoe before wearing it and adjust once the shoe fits. The FAST H2O offers a seamless fit that adheres like a second skin, preventing water penetration and improving aerodynamics. The added reflective logo increases visibility during your workout.
