I went to the running store and got on their machine had someone check my feet and got fitted for new shoes. I wore them yesterday to walk around in just to get the "feel for them", Brooks pure cadence. My feet ached so bad and now my back is killilng me! What the heck, Isn't the point of getting fitted to guarantee that you have the right fit? Has anyone had this happen? I hope they will take them back. I just do not know what to do now.
