This used to happen to me when I ran, and is one of the reasons I gave running up.

My experience was that, after a few miles, my toes started to get numb and/or tingle. I experimented with different shoes and tying the laces tighter or looser. At one point, I had the laces so loose that the shoes barely stayed on.
I also tried different running methods, like focusing on landing on the balls of my feet. But nothing ever worked.

Eventually, I chalked up the whole thing to poor circulation.

Now, I use the elliptical machine, generally for a full hour (and half of that time I do an interval program, trying to mimic real sprints intermittently). I never experience the numbness or tingling sensation.

Wish I had some answers, but I don't. This is just my experience.
