Welcome The Winter Warrior

Usually shopping for socks is more of a chore than anything else. And searching for the perfect sock to wear during long winter rides? Forget about it! Luckily, the creative team at Castelli noticed this issue and created the Fuga 18 Sock for cold-weather riding you can feel good in, from head to toe.

These heavy-duty socks start out with a winter-weight blend of merino wool, which delivers the warmth and comfort you rely on with the moisture control you need for an effective training session. A midfoot support band across the arch provides compression that keeps your foot activated and prepared to pedal, while a nylon heel and toe deliver on durability for mile after mile.

Take on low temperatures with the socks born to perform. The Fuga 18 also features an 18cm tall cuff that won't ride low when tackling the roads or mountains. With a simple design to tie it all together, this sock is hard to beat.


  • Winter-weight merino wool blend
  • Arch-support band
  • Nylon heel and toe for durability
  • Tall 18cm height
