FitFlop Women's iQushion Ergonomic Toe Thong Sandals Flip Flops, Black, 8.5

From the top, they look like your typical surfer-girl flip-flops. Underneath, they’re biomechanically engineered with our superlight, 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.
