I have a new pair of runners (had them about 2 weeks), and I am very picky about how they fit and how tight/loose they are, so I don't think that's the problem. Tomorrow I will see the doctor doing the study and I'll ask him.

Thanks for the input!
OK, my toes sometimes tingle after using an elliptical. When you run make sure that your foot rolls from your heal to your toes, not just on your "tippy toes" a lot of people make that mistake. I am sure it is nothing to worry about.
