Castelli Alpha 18 Socks CS2155362511

Castelli Alpha 18 Socks Castelli's Alpha 18 Socks will get you through the coldest rides. They combine luxuriously soft Merino wool with PrimaLoft®, resulting in an incredibly warm material, which remains breathable, moisture-wicking, odour-free and highly durable. The cuff is 18cm to cover more of the lower leg, and Nylon in the heel and toe areas prevents excess wear. A support band has been added to the arch to keep the socks in place and stops the bunching of material.
