Louis Garneau packed the right balance of stiffness, weight, and comfort into the Men's Course 2LS Shoes for you to ride full speed ahead. To start, Garneau updated the outsoles to Exo Jet Carbon, giving the 2LS lighter and stiffer soles than the comparable Carbon Pro Team's HM X Lites. These outsoles also feature a thinner construction and make for a lower stack height to increase power transfer. Air channels run from toe to heel to ensure there is always a source of cooler air running over your feet during hot summer rides. On top of that, the shoes use a microfiber upper with mesh ventilation windows to increase breathability. Thanks to the shoes' Double Boa L5 closure system, you have a huge advantage over other shoes. Now you can control volume, eliminate contact pressure points, and you lose weight at the same time. Dial in the perfect fit before you ride and anytime you want to adjust on the fly. The Men's Course 2LS Shoes also use HRS 300 technology to keep your heels from shifting, preventing any loss of power while pedaling.
