I'm thinking of purchasing some Newton running shoes. I have flat feet, with a slight pronation, 5'6", 185 lbs. I've been using Nike Vomero 2's for the last couple of years and they've been really good. I have a pair of Vomero 3's and they feel different than the previous. I wan't to get away from Nike since they don't last very long. Anyone out there with similar feet who have tried the Newtons? What are your views?
