Madewell The Natasha Flatform Sandal 7.5 Sleek and stylish, these are the sandals we'll be wearing all summer long at Madewell HQ (with dresses, with wide-legged jeans...). Crafted from Gold-certified reclaimed vachetta leather, these strappy flatforms have a toe loop and chunky crisscross straps that wrap around the ankle. When you select your size, "H" equals a half size. 1" heel. Leather upper. Do Well: all leather, including some reclaimed from what would otherwise be waste, was sourced from a tannery that achieved a Gold Rating from the Leather Working Group (LWG), an organization that works to promote sustainable environmental practices in the leather industry. Man-made sole. Imported.
