When it comes to cool weather cycling, the Vancouver based Sugoi has had its knits dialed in for over twenty years. And the RS Winter Socks are the perfect example of how Sugoi's dedication to technical designs combat the chills of winter. Stretch fabrics and engineered panels allow the RS Winter socks to conform to the shape of your feet to retain warmth without limiting movement or compromising blood circulation. However, while keeping heat in is a relatively simple task, what's equally important, yet far more tricky, is the task of moisture management. That's why the RS Winter's fabrics are designed to actively transfer perspiration without dehydrating the skin. This ensures that your dogs stay warm and dry, even when pushing over a sweat inducing, late season alpine climb. For the long haul, denser cushioning at the footbed prevents the all to common hot spots from cleat abrasion. The front of the above ankle cuff also gets the thicker material treatment for added warmth on chilly descents and windy days. The Sugoi RS Winter Socks are available in the color Black and in the sizes Small, Medium, and Large.
