SAS CoolSTEP foot bed combined with a perforated design on the upper makes VTO a great Medicare and Diabetic approved shoe with enough ventilation to prevent heat under foot. SAS odor-resistant Tripad cushions lend additional support to the three primary pressure points of the foot. Added-depth allows plenty of room for the toes to spread out, and SAS EZ Strap allows a custom fit. Experience the support of VTO.
