Made for cooler temperatures, Thermeator creates a thin, lightweight layer of insulation inside the shoe. Made with ThermoliteĀ®, a fiber that helps retain

body heat. The insulation does create a tighter fit in close fitting cycling shoes than the Aireator, Cyclismo and Levitator do. Keeping feet warm during

those colder days on the bike helps conserve energy and increase comfort and performance.Ā
