The Castelli Scorpion Logo 20 Thermal Socks featured here at Escapa are thermal cycling socks designed to keep your feet comfortable during rides in cold weather. Their fabric, made with PrimaLoft® synthetic fiber, combines insulation, breathability, and effective moisture management.
Their mid-weight construction provides thermal protection without taking up too much space inside your cycling shoes. The 20-cm cuff extends coverage over the ankle and ensures a comfortable fit with long cycling shorts or leg warmers.
PrimaLoft Thermal Fiber
PrimaLoft synthetic fiber helps retain body heat and wick away moisture generated while cycling. This balance helps you stay drier and more comfortable as the intensity of your ride changes.
Moisture management is especially important during the winter. A sock that is too thick or not breathable enough can trap sweat, which in turn increases the feeling of cold during descents, stops, or lower-intensity stretches.
Medium thickness compatible with cycling shoes
Their medium-weight fabric provides insulation without adding excessive bulk. This allows you to wear the socks comfortably with road, Gravel, or MTB shoes, provided the shoes have adequate space.
A snug fit without excessive compression promotes circulation and helps maintain foot temperature during rides in cold weather.
20-cm cuff
The 20 cm cuff provides ample coverage for the ankle and lower leg. This height offers additional protection and helps prevent exposed areas between the sock and long cycling shorts.
The high cut also offers a sporty look and showcases Castelli’s signature scorpion logo.
Sizes based on shoe size
The socks are available in three sizes, based on European shoe sizes:
S/M: sizes 36 to 39.
L/XL: sizes 40 to 43.
XXL: sizes 44 to 47.
To select the correct size, use your usual cycling shoe size as a reference.
