Castelli Alpha 18 Socks: The Ultimate Fusion of Warmth and Performance for Winter CyclingElevate your cold-weather riding experience with the Castelli Alpha 18 Socks, meticulously engineered for cyclists who refuse to let dropping temperatures dictate their training schedule. Designed as the perfect companion to the Alpha RoS jackets, these men´s socks bring a new level of thermal regulation and comfort to your feet, ensuring they remain warm, dry, and comfortable on the longest, most demanding winter rides. Forget the feeling of cold, damp feet, the Alpha 18 is your essential barrier against the elements, allowing you to focus purely on your performance and the road ahead.The secret to the Alpha 18´s exceptional performance lies in its advanced technical construction. It features a sophisticated blend of high-performance synthetic and natural yarns, creating a microclimate around your foot that provides outstanding insulation without the bulk. This innovative fabric actively wicks moisture away from your skin, a critical feature for preventing the chill that comes from sweat cooling down. The result is consistent warmth and dryness from the first pedal stroke to the last, even during intense efforts. These are not just warm socks, they are a high-performance piece of equipment designed for the serious cyclist.Comfort is paramount on any ride, and the Alpha 18 delivers an anatomically superior fit. A dedicated arch-support band provides stability and prevents the sock from bunching or slipping inside your shoe, ensuring a smooth, efficient pedal stroke and eliminating potential hot spots. The 18cm cuff height is perfectly tailored for winter cycling, providing ample coverage that seamlessly bridges the gap between your cycling tights and shoes, effectively sealing out cold drafts. For enhanced safety during the shorter days of winter, a subtle yet effective reflective stripe is integrated into the back, increasing your visibility to others in low-light conditions. Built for the rigors of dedicated training, these socks are an investment in your comfort and performance.Attributes: Men, SyntheticEspeficitations:PrimaLoft® / merino wool blend.Arch-support band.Nylon heel and toe for durability.Reflective stripe on back.18cm height
