Size 43, my shoe size is normally 9 1/2 EEE Averaging over 100 miles a week Cycling My first pair of "ROAD" shoes. Replaced a pair of "wide" Sidi mountain bike shoes that were uncomfortable on every 25+ mile ride. My first ride was over 45 miles and 1300 feet of ascent. Much more convenient. Used my two bolt SPD spikes. Pedals and cleats are upgraded to a three-bolt system that is more compatible with road cycling shoes. They weren't even made specifically for my wide feet. Time will tell how long they last, but at this price you can change more often if needed.
