A Cycling Sock For The Stars

Socks designed for the hottest days in the saddle. The Superleggera T 18 Socks are the ultimate accessory to make your rides better than ever. Fitted with a light mesh on the ankle and top of the foot, this lightweight cycling sock helps any heat and moisture escape with ease. This keeps you comfortable as you ascend those long grueling climbs or step on the pedals to reach warp speed.

The 200-needle construction provides extra stretch, remaining soft and comfortable even after a long day under the sun. A midfoot support band holds the socks in place, ensuring that they won't fall while you go hard on the pedals. Meryl® Skinlife antimicrobial yarns with silver ions reduce odor and keep your feet feeling as fresh as the 18cm high cuff is looking.

  • Lightest mesh ankle and top of foot for hot-weather comfort

    Very thin & lightweight

    Very thin & lightweight. Good for summer & leave plenty of room in your shoes for feet to swell. A little too much compression but bearable.
