The “Uni Kous” from Stanno has a good fit thanks to the “highly stretched” polyester it is made of. For optimal breathability, the sock on the calf has a mesh insert and there is also a protective impact zone around the ankle. The sock has a flat hem which prevents chafing (and therefore also blisters). The heel, sole and toe are also reinforced. The “Uni Kous” stays in place thanks to the double elastic band.
