Socks come in many styles, cuff heights, and fabric blends and the Castelli Superleggera 12 is one that places a premium on hot weather performance counterbalanced by comfort and features that pro cyclists desire. The heart of the sock is an innovative nylon yarn containing silver micro-particles that reduce unpleasant odors. Meryl® Skinlife yarn is soft and lightweight . It is hypoallergenic, and works to maintain the natural balance of the skin. The yarn guarantees maximum comfort and performances, which is why it has become one of the most demanded yarns in premium grade sport-specific socks. The yarn also allows for incredible knits and structures. Hence the defining feature of the Superleggera 12 Sock: the ultralight diaphanous mesh ankle zones that support and comfort, while allowing cooling airflow.
The 12cm cuff is still tall historically, but tame by modern standards. It is a perfect moderate height that offers some crucial support and a super clean fit. A center standard knit runs up the Achilles for added mild compression. While each zone of the Superleggera 12 employs a different knit and overall fabric weight based on requirements, all feature the Skinlife yarns. A midfoot support band adds some arch support and carry the Castelli wordmark vertical logo, while a reinforced heel and forefoot are joined for greater overall cushion. An open mesh fabric sits above and below the midfoot support, with a finer mesh traveling up the front of the ankle, which transitions to the mesh. The cuff band is flat and offers great hold. If you like cool socks, or have the sensitivity to assess how well a sock performs as you extend your efforts, you will appreciate the Superleggera 12.
