What Our Gearhead® Experts Are Saying: “These quickly became some of my favorite endurance socks. They’re super light and breathe incredibly well on hot days, and the cuff compression feels supportive without being tight. The silicone grip at the top is a game-changer—no slipping, no wrinkling, even during long climbs or out-of-saddle efforts.” We choose the Assos GTO Socks S11 when long, warm rides demand breathability, support, and all-day comfort. Their lightweight construction keeps our feet cool through steady climbs and long stretches of sunbaked tarmac, while the traditional ventilated yarns across the foot create reliable airflow when temperatures climb. The gentle compression in the cuff provides a supportive hold, and the silicone grip ensures the sock stays perfectly in place without bunching or wrinkling. Thoughtfully designed for endurance cyclists, these socks balance stability with comfort, giving us a low-bulk feel that works effortlessly inside stiff cycling shoes. When the miles stretch long and the heat ramps up, the GTO Socks stay cool, supportive, and securely locked in.
