Running through a UK winter is a test of patience, persistence and gear choice. The cold isn’t always extreme, but it’s persistent, wet and often bone-deep. One day you’re dealing with a damp chill that seeps into your bones, and the next you’re dodging puddles and battling gusty winds. If you’ve ever felt your toes go numb halfway through a run or finished a route with soaked socks that felt twice their weight, you already know how much your feet suffer through these months.
