Less than 1% of all socks worn in the USA are actually made here. This is why Sleet & Sole set out with a mission to manufacture sustainable socks that are 100% made in the USA. They design and manufacture a range of eco-friendly socks from their factory in New York. Their Repreve socks are each made in the USA from 3 recycled plastic bottles and American yarn. Other socks are made from recycled bamboo or recycled cotton, and they also sell bamboo and merino wool socks where the wool is sourced from small farmers in North Carolina. Using only sustainable yarns and sourcing products locally means they are helping protect the earth one sock at a time!
