Castelli Logo Winter Sock

On long rides, the moisture wicking fiber in the Castelli Logo Winter Sock will keep your feet dry and comfortable. The Thermolite fabric keeps your feet warm on days when the temperature drops. The ideal fit for a road shoe is also found in the flat-knit construction, which not only makes it a warm but also a light sock. A 9-cm. cuff and mid-foot support band, make this sock stylish and comfortable.
