Spenco® polysorb® total support sandals combine the support and stability of our best-selling insole with the comfort and simplicity of a slip-on sandal. great for after sports or training or just kicking back indoors or out. unlike some other slip-ons, spenco® sandals are designed with orthotic-quality arch and heel support. superior impact cushioning and motion control help reduce pronation and supination—common problems associated with flat, slab-style sandals. available in a range of sizes for men and women, and three styles.
