I'm still working on this one. I have the rest of me toasty warm down to 15F, but no matter what I do when I get to work (a little over an hour), my toes are cold.

I have tried thin socks, thick socks, thin socks with thick socks, winter cycling boots, and, heck, even Keen cycling sandals (which, btw, with a thick sock worked as well as my cyling boots down to about 35F).

My last foray into finding the toe warming miracle was based on a woman over on another forum. She stated that the secret to keeping fingers and toes warm was to keep the pulse points warm (wrist and ankle).

While it sounded silly to me, I did notice that my fingers stay warmest if I make sure that my gloves overlap my jersy and I batten down the velcro on my jacket to hold it all in place. So, what the heck.

I followed her suggestion of a neoprene ankle support to keep the ankle warm. Being the closet scientist (and cheap), I bought one support and wore it on one foot with a wool sock and just a wool sock on the other. Thirty minutes into my commute both toes were getting cold. By the time I got to work....no difference.

Next week, I'm going for wool knee socks and knickers instead of shorts under my tights. I guess I'm thinking along the lines of ny biker -- I'm going to make sure my legs are warm and see if that translates to warm feet. Can't do the one leg experiment, but one thing about the commute is there is always the next day to try something else.
