"Newton trainers have totally revolutionised the way I run," Kerry McCarthy says. "They're designed to help you land on your forefoot, which is how you would run naturally if barefoot. It took me a couple of months of sore calves to adjust, but after that I picked up far fewer injuries. They also have an energy-return system in the sole which helps you run faster with less effort. Not everyone is a forefoot runner but if you are then there's no better shoe."
