Lake's CX237 Road Shoes are designed to be both comfortable and brutally efficient, a line not often walked this gracefully in the footwear department. To close the shoes, you'll find two Boa reels, able to be adjusted independently so you can lock in your heel without strangling your forefoot. But the upper that closes around your foot is made from full grain leather, a choice made for comfort and a supremely personalized fit. It'll only get better the more you wear it. The sole is Lake's Race Carbon. It's a carbon fiber sole built on Lake's Competition last, which is designed to direct all of your power output through the ball of your foot, but still allow a bit of wiggle room when your feet swell.
