From the top, they look like your typical surfer flip-flops. Underneath, they’re biomechanically engineered with FitFlop's featherlight, pressure-diffusing iQushion™ midsole tech. Made of high-rebound air-foam that retains its cushioning, with heel and ball-of-foot impact pillows, and a contoured footbed for natural support when you walk. Anatomically shaped straps hold the sandals to you, to help stop toes gripping. Throw a pair in your suitcase and you’ll find yourself wearing them to beach, bar and beyond. Waterproof and slip-resistant. Sizing note: These iQushion flip-flops fit slightly small. If you fit between sizes, FitFlop recommend that you go up in size rather than down.
