Just like our top selling eco-cotton and eco-wool watchcaps, these socks are made from recycled cotton, wool, and P.E.T. bottles. Equipped with extra cushioned arch support & a OSFM stretch fit from sizes 8-12, these socks are ready for sport & leisure. Three classic colors to choose from make it hard to pick just one! ***** NOTE THERE IS A TYPO ON THE BACK OF THE PACKAGING THAT SAYS "MADE FROM UPCYCLED COTTON..." AND IT SHOUD READ "MADE FROM UPCCLED COTTON AND WOOL..." The white and colored stripe is made from our signature upcycled cotton and the grey is upcycled wool.
