LIGHT & DRYOur polypropylene Logo socks are made especially to feel light on the foot & to keep your foot dry. The yarns absorb no moisture so your foot stays dry for the entire ride. These socks are ideal to be used under booties in the rain since they dry out quicker after it stops raining. As with all Castelli socks weve obsessed over the compression cuff & midfoot band so everything feels just right. Polypropylene mesh construction Compression ankle band
