DeFeet Sock Company continues to produce the finest socks. This is the first company to create socks with CoolMax EcoMade, fiber made from used recycled plastic bottles. The performance of DeFeet socks with these fibers is excellent and customers understand the story immediately. The inclusion of EcoMade fibers to more of the DeFeet socks line represents much more than the small net gain for the environment. After all, DeFeet is a small, custom crafter. They believe that by telling this story to as many customers’ and companies as possible, the gains can be exponential.
