Do your feet roll inward?

Biomechanics specialists changed their assessment of pronation, or the tendency of your feet to roll inward while running which has previously been blamed for many injuries. In his book Biomechanics of Sport Shoes, veteran Canadian biomechanics researcher Benno Nigg explains that pronation is an entirely normal phenomenon. In fact, it’s the way humans are designed to walk and run. Excessive, harmful overpronation is rare, Nigg says. A 2014 study in the British Journal of Sports Medicine confirmed his position by following 927 novice runners for a year and finding that the pronators had, if anything, fewer injuries than non-pronators. This means runners who are used to buying shoes based on the height of their arches or the advice of salesmen who have watched them run across the store to gauge their pronation tendency need a new strategy.
