I'm using platform pedals now, and just got some BIG sorel boots, with room for three pairs of wool socks and I can still wiggle my toes. I can keep my feet warm for an hour and a half. It is the last hour that kills me. I tried some new chemical warmers, and they seemed to work better. My "Little Hotties" give out after an hour and a half; these "Hot Spot" warmers were still going strong hours after my ride. I also got some aerogel insoles, and they seemed to help. I survived a 3 hr ride at -14°F, so I guess I shouldn't complain.

The problem is not lack of insulation, the problem is pressure on my feet squeezing all the blood out. I know I should "spin" more, but have you tried spinning while riding Sorels? The boots alone weigh 5 or 6 pounds. If I get off my bike and walk it for a half mile, my toes warm up, even though my heart rate goes way down. But stopping and walking makes my commute even longer . . .and I might even start to get Angry at Winter!

Next thing I'm going to try is some energy bars made of that Purina Ape chow. Ape Chow . . . mmmmmm. Makes me warm just thinking about it.
