Castelli Quindici Soft Merino Socks

What Makes the Quindici Soft Merino Sock Worth Wearing? The Castelli Quindici Soft Merino Sock brings natural fiber performance to the cycling-specific sock category, combining the thermal regulation of merino wool with a construction tuned for long days in the saddle. The merino wool blend keeps feet warm without trapping sweat, naturally wicking moisture and preventing the cold-wet combination that makes winter rides miserable. The 15cm cuff height provides generous leg coverage and sits cleanly under a bib tight or knee warmer. These are the socks you reach for when the temperature starts to drop. Compression zones in the arch and ankle provide light support and hold the sock in place over long efforts without restricting circulation. The reinforced toe and heel construction adds durability in the highest-wear areas, extending the life of the sock through hard use and regular washing. The soft merino blend resists odor naturally, making these a practical choice for back-to-back training days. Sized for cycling shoes, these socks deliver a snug fit that does not bunch or slip inside the shoe.
