I am having the exact same problem! It happens on an elliptical (which makes sense, as many of you have stated, our feet stay in ONE position)...but I noticed it's also starting to happen to me of just 20 minutes of a quick-paced walk, too. It slows me down because the numbness almost turns painful (like pins and needles).

I noticed that someone mentioned the possibility of it being poor circulation - and my mother had a circulatory disease which is hereditary. Kind of put me on alert. Should I check this out? I'm hoping this is just as normal as everyone else's strange numb sensation.
