Rock Your Ride

Prepare for the ride of a lifetime with comfort and performance from head to toe. The Castelli Alpha 18 Sock pulls all the stops to create a garment that not only delivers quality and power but also style to your daily commute or weekend shenanigans.

A heavy-duty construction relies on the use of both PrimaLoft® as well as Merino wool to create a layer that delivers the perfect amount of warmth. This unique blend is also quite moisture-wicking, keeping your feet dry and odor-free. A support band along the arch maintains proper flexion and keeps your feet comfortable with every pedal.

The Alpha 18 socks are perfect for any style of ride, both day and night. The nylon heel and toe promote durability so you can go full-throttle down the gravel trail, while a reflective stripe on the back allows you to be seen in low-light conditions.

Features:

  • PrimaLoft® and Merino wool blend
  • Arch-support band
  • Nylon heel and toe for durability
  • Reflective stripe on back
  • Remarkable 18cm height
