We set out to source materials with a goal of being kinder to the earth. The result: a mix of repurposed, recycled, and organic cotton, plus a blend of polyester, nylon, and elastane to create a supportive fit and cushioned Blister Tab. The use of repurposed and recycled yarns also creates random batches of these socks—sometimes they’re all different colors, sometimes a few are the same. You won’t know what yours look like until they’re in your hands.
