Check out these socks made from recycled yarn from Japanese company MUJI. These socks are really neat their colors are wacky and cool and they fit well. I had a pack given to me from the MoMA store in NYC and I wear them regularly – the socks are available @ MoMA or from MUJI stores on or online. MUJI is often described as a “Japanese IKEA” however they carry a wide range of men’s and women’s clothing. The company has many sustainable practices including using recycled cardboard in many of its products, using unbleached cotton and practicing sustainable forestry.
