Louis Garneau's Course Air Lite XZ Cycling Shoe pushes the envelope of high performance. We like this shoe because of its stiffness and ventilation, which are a huge benefit in both racing and training. Louis Garneau increased arch support and power transfer so we can keep comfortable and never waste watts. A ventilated and expandable zone ensures accommodation for B to D+ foot widths to prevent numbness, and LG's new under-lace woven system keeps dirt out from under the shoe's guides. The Course Air Lite XZ Cycling Shoe is made to be durable without sacrificing comfort. We like that this shoe's stiffness improves power transfer and, whether we're pumping out big miles or facing challenging training days, we're happy to be sporting the Course Air Lite XZ Cycling Shoe.
