From the top, they look like your typical surfer-girl flip-flops. Underneath, they’re 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. This version adorned with sparkling micro-'crystals', throw a pair in your suitcase and you’ll find yourself wearing them to beach, bar and beyond. Waterproof and slip-resistant. 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.
