From the top, they look like the cutest fluffy flip-flops. Underneath, they’re biomechanically engineered with our iQushion™ midsole tech. Made of high-rebound air-foam for non-stop cushioning, with heel and ball-of-foot impact pillows, and a contoured arch-curve for natural support when you walk. In cushy cotton toweling (non-wicking) that's supersoft against your feet. Brilliant by the pool, for spa visits, or just padding around in your bathroom/bedroom. Because of the design of this version, iQushion charms do not fit on these flip-flops. Sizing note: These iQushion flip-flops fit slightly small. If you fit between sizes, we recommend that you go up in size rather than down.
