Cozy and plastic are two words that don’t often go together. But it just so happens that polyester from recycled plastic makes THE WORLD’S BEST SOCKS. Our combo of super-stretchy yarn and an intricate waffle design feels silky smooth and does two important things: helps your socks stay put and keeps your toes (and legs) snuggly warm. Sustainability truly meets luxury in these beautiful and cozy socks. To top it all off, four recycled plastic bottles are used to make these socks.
