I have really bad feet! My feet doeson't seem to hurt much when I do long walks in FLIP FLOPS. But when I wear actual tennis shoes WITH my orthodics, ( or without) they hurt sooooooooo bad...it feels like needles are pinning at my feet. Then I end up limping home. I have flat feet. Does anyone else have this problem? What do you do? It's sooo hard to go running when I can't even last for more than 2 mins without quitting.
