Scorpion Logo 20 Thermal Sock

What Our Gearhead® Experts Are Saying:

"I reach for these on any ride where the forecast refuses to climb above freezing. The tall cuff eliminates the ankle gap entirely, and the PrimaLoft yarn kept my feet dry through hours in the saddle."

Castelli engineered this sock around PrimaLoft® yarn, prized for delivering real warmth alongside genuine moisture transfer rather than insulation alone. The mid-weight knit is built to slide into a standard cycling shoe without adding bulk that throws off the fit or feel on the pedals.

A 20cm cuff height pushes coverage well up the ankle, guarding the exact zone where cold air tends to sneak past a jacket hem or bib cuff during long efforts in harsh conditions.

This is the sock for the ride where the forecast doesn't budge above freezing, built to keep ankles out of the conversation entirely so the only thing left to manage is the road ahead.
