Go to a specialty running shoe store, not one of the box stores. The specialty store knows there products very well and just by asking a few questions and watching you walk they will know which shoes are best. If you do not know of a store near you ask one of the track or cross country coaches. Here is a good thread from the past http://www.serviceacademyforums.com...p-for-plebe-summer-running.48179/#post-478658
My son got his last pair of shoes that way. They are by far the best, most comfortable running shoes he has ever had.
