Joya Susan Leather Women's Sandal Full grain leather upper with breathable mesh lining. Three fully adjustable straps for maximum stability and comfort. The Joya sole is made from two pieces of PU, softer on top and firmer below. Both encapsulated by a very thin and durable film (made by 3M). The softer provides cushioning and the firmer support/stability as the foot strikes. The two combine to provide a cushioned stable rebound effect as you walk. Joya shoe absorb shock and move you forward. Thick yet supple leathers without additional dyes keep the leather breathable, durable and comfortable.
