I'm a distance runner. When I had injuries, better shoes fixed them. I spend ~$400/yr on shoes. If you run enough mileage, they help. If you don't, they aren't

I'm a distance runner. When I had injuries, better shoes fixed them. I spend ~$400/yr on shoes. If you run enough mileage, they help. If you don't, they aren't worth your investment. Also, sprinters seem not to require as much cusioning as they require stability.
