I'm a 55-year-old ex-jock that looks in the mirror and sees a 35-year-old. I have returned to running in the last two years. I run in any season and weather condition. Rain is no deterrent. I hated the extra wet and swish of wet shoes. The XCRs meant no extra weight in wet weather and completely dry feet. I usually wear 13 but need a 1/2 size larger in many brands. I anticipated this and purchased 14 which are not in the least too big. The fit is perfect when laced properly. The shoe feels like a road racer. THE IS NO OFF SEASON OR OFF DAYS. Train to livelive to train!
