If you"re of the mindset that socks are "just socks," we feel sorry for your feet. Although, there are the occasional nuts that can ride sock-less for centuries at a time, us mere mortals need a strong layer of defense between our shoes and our skin. This is where the Louis Garneau Course Socks come in. Made from a blend of Coolmax, Meryl Skinlife, nylon, and Lycra, the Course socks provide an ultra-thin layer of slightly compressive protection. This support will aid in a more positive bloodflow, resulting in the minimization of the dreaded "numb foot." Even further along these lines, the double-layered tall cuff features a seamless design that eliminates pressures points and retains support for the aforementioned compressive system. For extra support, Garneau incorporated an elastic cuff over and under the center of the foot. Additionally, the toe and heel have both been reinforced to combat the two main points of abrasion. Just as importantly, the fabric blend is lightweight, airy, and quick-drying. So, your shoes" volume won"t be impacted, and you can ride with confidence in the Course socks" ability to wick away sweat. The Louis Garneau Course Socks are available in the colors Black and White and in the sizes Small/medium and Large/x-large.
