With sexy in the title, you can't discuss these socks without first mentioning their sleek, fitted, and overall desirable good looks. The socks were designed with Castelli's most technical yarns to keep your feet cool and dry, while at the same time looking, well, sexy. Castelli constructed the Sexy Socks out of Meryl Skinlife antibacterial fibers. This is a polyester and anti microbial knit that adds significant life span to socks by blending bacteriostatic silver particles at the fiber level. This means that when the socks are washed, dirt and sweat go down the drain, but the technology that you paid for remains intact. In addition to the benefits provided by Meryl Skinlife, the front mesh panels and mid foot straps of the Sexy Socks give you the perfect amount of ventilation and support for all of your warm weather rides this season. The Castelli Sexy Socks are available in sizes Smallmedium and Largex large and in the colors Blackpink fluo, Blackwhite, Whiteblack, and Whitecyclamen.
