When you're working out, you shouldn't think twice about your socks. They should be so comfortable you forget they're there, and they should do their part to enhance your performance. That's what these socks from adidas by Stella McCartney have down. Arch support shapes the toe, heel and arch, and a cushioned footbed gives you a soft spot to land. Made with no animal ingredients, they're soft, stretchy and cut low for a clean look.
