I just got a pair of New Balances recently, which were basically a newer model of my old shoes (which I loved). However, during my break-in period, I noticed that i was feeling an intense burn after a couple miles of running in the arch of my foot. I thought it was just the shoes, since they haven't been broken in yet, but after the break-in period, I still feel that burn after a while. I wore them to the gym yesterday and even walking around it was uncomfortable in the arch. It's probably too late to return the shoes, but do you guys think a new insole would help? Or is the shoe just not broken in yet?
