Designed to be used with boots built on our 650 last

Extra support worthy of the experts we serve, the Airthotic is a half- length, molded polyurethane instep that cups the heel and supports the arch area of the foot. More rigid than a foam footbed, the raised arch support won't compress over time, and is perforated for improved air circulation and comfort. Designed to be used with boots built on our 650 last.
