Description
The Castelli Alpha 18 Sock keeps our feet and ankles warm and protected as we continue to put miles in on our bikes during the cold winter. Its merino wool blend and PrimaLoft insulation keep our feet from freezing while also ensuring we don't overheat, thanks to its breathable and moisture-wicking properties.
