The Boyes sandal is the ideal motion control footwear for after-sport recovery. The durable outsole offers excellent traction on various surfaces, and the biomechanically contoured, motion control footbed offers stability in the rear foot and cushioning in the heel and forefoot. The flexible uppers feature fully adjustable straps with hook-and-loop closure and a soft padded jersey liner. Received APMA Seal of Acceptance. Recommended by Dr. Andrew Weil. For the greatest comfort, we recommend wearing your new Vionic footwear for just a few hours for the first few days to allow your feet to adjust to the new level of orthotic comfort and support. Within one to two weeks you should find the product completely comfortable and supportive.
