Racing Socks These socks were used for running practice and races, so they show some wear and tear. They are being sold as used items, so please refrain from purchasing if you are concerned. An evolved version of the popular Racing Run 5-finger socks. Despite the thin fabric, these socks offer even greater support and breathability than before. The toe and heel areas feature a "double-layered structure" with Deocell, which has excellent sweat-wicking and deodorizing properties, on the skin side, and durable nylon on the outer side, which receives friction from the shoes. The combination of these two materials supports comfortable running. * Durable nylon used. * Uses Tabio's original sweat-wicking and deodorizing yarn. The fabric is thinner and lighter than the previous Racing Run 5-finger socks, supporting comfortable running!
