GTO Socks S11

What Our Gearhead® Experts Are Saying:

“These feel purpose-built for endurance riding. The breathability is top-tier, and the cuff compression gives just enough support without feeling restrictive. The silicone grip holds them perfectly in place, which is huge during long efforts or when you’re constantly shifting body position.”

The Assos GTO Socks S11 are precision-engineered for endurance cyclists who need consistent thermoregulation and stability during warm, high-intensity efforts. Their lightweight fabric blend promotes maximum airflow through the foot, offering critical cooling during long climbs, exposed gravel stretches, and sustained tempo riding. The ventilated traditional yarns deliver reliable moisture transfer, ensuring the foot remains dry and comfortable inside snug cycling shoes.

At the cuff, a combination of gentle compression and integrated silicone grippers provides structured support while eliminating slippage and wrinkling—a key advantage during long saddle hours or aggressive accelerations. The low-bulk design enhances shoe contact and power transfer, making them ideal for riders who demand precise responsiveness.

Purpose-built for warm-season endurance riding, the GTO Socks S11 deliver cooling performance, stable support, and seamless integration with high-performance footwear across road, gravel, and long-distance training.
