Short socks have definite advantages: They are especially light and comfortable, and they do not trap excess heat. But the shorter the sock, the greater the risk of its slipping down into the shoe. Now there is a solution to this pesky problem: our special pull-on non-slip flap. After adjusting the sock for optimal comfort, the flap is pulled over the top edge of the shoe. This keeps the sock in place and prevents it from slipping down into the shoe – minor detail, huge effect!
