Socks: Upgraded

Assos GTO Socks are an all-new premium sock that defines elegant performance and endurance comfort with every pedal stroke on every ride, merging the concept of lightness and the sensation of coolness.

Though shorts and jerseys get the most attention for comfort and performance, the humble sock wraps one of your body's most important contact points with the bike. So Assos designed a performance endurance sock that's anything but humble. They gave it the attention it deserves with a premium reengineering, incorporating silicone grip and a luxurious Sens ST fabric to elevate utility to art, setting the GTO Sock apart as a truly unique piece of cycling equipment.


  • Engineered to breathe across the top and cushion the pedal stroke with light padding below the forefoot
  • Sens ST on the cuffs combines gently wrapping compression with a touch of breathable, ultra soft comfort
  • Traditional yarns across the foot provide breathability and support
  • Printed silicone finish prevents wrinkling
  • 15cm (6in) cuff height balances trend and tradition.
  • Foot: 80% Polyamide, 20% Elastane / Ankle: 72% Polyamide, 28% Elastane
