Northwave Men's Aerlite 3 Road Cycling Shoes feature power transmission, ventilation, heel retention, and an anatomic fit to help you have an amazing ride. Three layers of carbon on the sole make sure these pro-level cycling shoes stay stiff and responsive, while a three-strap design and the Ultra Y Heel lock your feet down so you don't lose power on the upstroke. The Aerlite 3's wood lasting insole has a flexible layer of thermoformed wood that molds to your foot and supports your arch, and a stiff core that improves power transmission. The wood insole also dampens vibrations and isolates your foot from the outsole to avoid overheating.
