These our one of our most popular shoe covers or "booties" because they are fantastic in a variety of situations and should be in every cyclists gear bag. The Barrier Lite Shoe cover provides a lightweight, protective covering for cyclists wanting an aerodynamic advantage or protection on cool, windy days. They are very popular with time trialists and also offer some rain protection for those choosing to ride on wet days. They feature a new, pull-on design that is simpler to use and also lighter.
