Having problems with my feet. I have been running for years, ever since the military. Went from running treadmill over the winter and now I'm back outdoors and it feels nice out. Problem, I am having pains in the arches of my feet. I was in the infantry and thought I had walked these arches flat(who know). My shoes are new but they where cheap. They are riddel trail runners. I am wondering maybe the trail runners ain't made for highway miles. My feet don't hurt when I run short distances like 2 miles, but when I do longer like 4 - 6 - 8 I get small pains the next day. Any advice would be appreciated. If all else fails I will get new shoes. That seems to be the obvious.
