I am having the hardest time finding comfortable running shoes. I think I must have a weird gait. My left foot is comfortable in any shoe but my right foot seems to have issues. I'm thinking I might have an instep (not sure if that's the right word). It's almost like the arch of my foot is hitting the side of the shoe, rather than the built in arch where it should hit. Is there something wrong with my feet? Any suggestions? Anyone else have this problem?
