One size 35 to 40 EU JAPANESE QUALITY: Made with Japanese Jacquard Technology. The seams are fine and soft to the touch to prevent chafing on the toes, heel, and cuffs. ALL-DAY COMFORT: They are stretchy and easily adapt to a wide range of sizes. Designed for wearing at home, for sleeping, and for use with footwear. SECURE FIT: The elastic cuffs prevent the sock from sliding and slipping down.
