The Kilpi BORENY-U socks ensure high climate comfort thanks to an elastane knit, synthetic fibers and a seamless structure. The thin and breathable material is ideal for intensive summer sports. Sensitively placed functional zones offer you support and increase the enjoyment of your training. The wide elastic upper hem does not pinch and does not prevent the blood circulation. The fixing instep hem holds the sock in place. The mid-calf socks are ideal for cycling or skating. You can choose from several colourful variations.
