Yesterday I had a full analysis and bought a new pair of running shoes. At the end of the analysis they made a custom insole and used that in all the shoes I tried on. I had a two-year-old pair of berry Super Feet in my old running shoes. I went from a a Brooks Dyad (stabilizing shoe I think) to a neutral Adidas. The fitter said my right foot is "normal" but my left has more flexibility in the ankle and the arch is slightly high. At the end of the fitting, they wanted me to buy the custom insole for $70, but I declined, since I'm not running very much and that would have put me way over budget. I went running last night in the new shoes with my old insoles and experienced shin pain and medial leg pain in the left leg and some in right, both things I didn't experience in my old shoes.

Any thoughts on what to do? Return the shoes? Go buy their insole or new Super Feet? I don't know much about running, as I'm mainly a cyclists just doing some running in the off-season.
