Sidi's Ergo 4 Carbon Men's Cycling Shoes are an investment, but the iconic brand hasn't earned its reputation making overpriced, overhyped shoes. With replaceable parts and thoughtful construction, Sidi shoes are made to last you seasons of hard riding. The Ergo 4 is a newer offering from the classic brand, and its carbon composite sole and incredible range of adjustability from Sidi's Tecno 3 buckle system promises to keep your feet happy and your hard earned watts delivered on time to the pedals with every turn of the crank arms. Sidi shoes are known for being built with a range of small extras that make life a lot easier in the saddle. In case you don't dial in just the right fit from Tecno 3 before you clip in, the buckles are easy to reach for and adjust from the saddle, and while you're mashing the pedals down to reach the crest of a climb, Sidi's Adjustable Heel Retention Device will keep even the boniest heels locked firmly in place so you don't waste power. The padded tongue keeps your instep free of frustrating pressure points, and the ventilated uppers keep air flowing freely between your toes.
