The Upcycled Sock may seem like a simple sock, but it was a long time in the making to work out the yarn and production of this 100% cotton sock. The Upcycled Sock is made in North Carolina out of 100% upcycled cotton. The cotton blend is 'plated' (a stretch yarn behind the main knit) to give stretch to the 100% cotton knit while also retaining its shape. The cotton is heavy enough for outdoor activities but still incredibly breathable to keep your feet fresh on warm days. OSFM 7-12 (Women's 7.5/8+) SUSTAINABLE MATERIALS BREATHABLE 100% COTTON The wide variety of colors to choose from makes it hard to pick just one while providing the perfect complement to any outfit in your wardrobe. Upstate Stock is a unique company founded on the belief that New York State’s long tradition of manufacturing is far from dead.
