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 Cyclismo was originally made under the direction of a World and Olympic Road Race champion who wanted some cushion under the balls of their feet.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. Available in 1", 3" and 5" cuff heights. Try a pair in your cycling shoes and you may find the feel of the Cyclismo to be your favorite.
