So before I go to the Dr. (which I am doing next week) I thought I would ask. For the past couple winters sometimes when I go for a run, my left foot goes numb after about 30 minutes of steady running. The kicker is this doesn’t happen all the time. And I know it isn’t because my shoes are too tight or that my foot is cold since if I stop and just stand there, the feeling in my foot does return. And I have plenty of room in the shoe as I can wiggle my toes and everything feels fine.
This never happens in the summer. As much as I would love to attribute this to the cold, I can’t understand why it wouldn’t happen to both feet and why it goes away when I stop running.
Any ideas?
Ideas? Sure, lots! How long until the “numbness” wears off? Where does it feel numb - bottom, toes only, top? And is it truly numb (can you still a pin in your skin and not feel it) or just that feeling of fullness/paresthesias? Any inside ankle pain with this? History of other vasospastic issues (i.e. Raynaud’s phenomenon)?

I was hoping you would pipe in. The numbness starts at the outside bottom and works it way all over the front of the foot. Covers the entire area (top and bottom) of foot if I keep running while it is numbing up. I haven’t tried a pin but I have taken the shoe off when it gets really bad and when I first rub the foot it doesn’t feel like I am rubbing anything at all (no feeling). No pain associated with the feeling at all.
If I stop running it takes about 3-5 minutes before the foot feels completely normal again.
I have no history of anything that I know of. 
It just frustrates me since it has never happened in the summer months and doesn’t happen every time I run in the winter.
I think this happens to my brother and I’d really be interested in what you find out. Please follow-up on this after you see the doc.
Thanks.
