I'm a new runner and training for my first half marathon... I have recently started running on my mizuno inspire 9. And after 3 separate runs, and around 13 miles in total, my left foot is totally bothering me. It hurts when I step and when I twist it around. Its not really swollen tho. I went to a foot reflexologist and it was nothing but a foot massage, it did give me some ease but didn't fix the problem! Goint to a sports medicine doctor now. But any thoughts on whats wrong and what I can do to prevent this from happening again? Any insight would be very helpful.
