Wally is Hey Dude's best-seller, designed to be your favorite shoe for all occasions! A variety of upper materials allow for year-round wear. The last shape, combined with Hey Dude Flex and Fold sole system make it the lightest, most comfortable shoe on the market today. Wally's low-top, chukka-style forefoot vamp is wide, allowing total circulation of the toe area, and a slightly lower instep arrests the foot preventing slippage. The heel pocket is anatomically correct, creating a superb feel even with custom orthotics. The memory foam insole is also lined with the natural wool fibers giving it a unique and stylish look to it while it adds extra comfort allowing you to go sockless. The insoles are removable for cleaning, and the shoes are machine washable. Hey Dude combines natural wool fibers with the design of their shoes to create the most comfortable and breathable material. The natural wool fibers also provide comfort in any environmental conditions allowing your skin to regulate its temperature. Features: Flex and Fold technology, ultra-light outsole, two lacing options, cotton canvas upper, natural wool fiber, memory foam insole, machine washable (cold) and 6.5 oz. total weight. Material: Cotton, Canvas, Wool, Memory Foam.
