These Sock Snob men's bamboo invisible trainer liner socks are handy, breathable, and super soft due to their high bamboo content. Bamboo fiber is luxuriously soft, moisture-wicking, and superior to cotton, helping to keep feet dry and reduce the chance of blisters. Perfect for wearing with boat shoes or trainers for a sockless look, these no-show socks fall below the ankle and are designed to stay up. They feature a 200 needle fine knit and the Sock Snob print on the bottom. Available in black, white, and natural, in two sizes: 6-11 UK (7-12 US, 39-45 EU) and 4-7 UK (5-8 US, 37-42 EU). Packaged with recyclable materials and machine washable.
