The UNI SOCK II is extra stretchy on the Tibia, so that the tibia protector can be easily placed. For optimum breathability, the sock has a mesh insert on the calf. The sock has a protective impact area around the ankle. And to avoid irritation and bulbs, the sock has a flat hem and a heel, a reinforced sole and tip. Thanks to the double elastic belt, the bottom remains well in place. This anatomical sock has a left / right indication.
