We pulled out all the stops with the Cyclismo. Made in both wool and ThermoCool™ versions. Cyclismo was originally made under the direction of a World and Olympic Road Race champion who wanted some cushion under the balls of their feet. The cushion serves many purposes. It takes up a little more room in the shoe, creating a tighter fit in the forefoot of cycling shoes than the Aireator. This helps dampen road vibration and eradicates any 'slipping' or movement of the foot inside the shoe. Try a pair in your cycling shoes and you may find the feel of the Cyclismo to be your favorite.
