Spenco PolySorb Total Support Yumi 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, 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 helps reduce pronation and supination—common problems associated with flat, slab-style sandals. Available in sizes: 6, 7, 8, 9, 10
