I have an old pair that I stuck in the closet after wearing them only a few times. I recently tried them again because I was having achilles tendon pain. They say to start running in them lightly because you need time to adjust so I've only been running in them for a mile or two at a time. When i run in them I have no achilles pain! The problem is they hurt my feet on the outside of the foot, just under the little toe. I figured the problem may be improper sizing so I am trying to order another pair in the next larger size. It seems as if Nike is no longer making them because all I can find is close out sales with odd sizes. My questions are: Has anyone found that this shoe cured your achilles tendonitis problem? Did you have any other injury problems that resulted from the shoe? Is Nike making a similar shoe under a different name? Thanks for any insight you might have.
