TheEndura FS260-Pro Nemo Overshoesuse superstretch waterproof thermal neoprene to keep your feet comfortable and protected. The idea of using neoprene as a barrier against the cold has been around since the 1950's in wetsuits, but was only recently adopted for cycling. The theory was; if it can keep you warm in near zero water submersion, it can keep your feet warm on the bike. Endura have proved this theory with these overshoes, helping keep your feet warm on even some of the coolest, dampest days.
