I need some help picking some new shoes. I've been on Barr Trail with my New Balance MT100, MT101, and MT10 shoes. My MT10's don't have enough protection for me, they're great for the uphill but my feet take a beating by the rocks on the downhill. Also, I'd also like more traction than any of these New Balances have. I'm trying to decide between the New Balance MT110 or the Brooks Pure Grit. Anyone have any opinions?
