At work, we have a Fitness D'base and I found it a good source of advice from other (mainly male) cyclists. This morning, someone started a thread, asking for tips on how to keep his hands/feet warm during these cold morning bike commutes. One of the guys---an experienced commuter---suggested putting plastic bags over his socks. Who'd have thunk it? I know that neoprene booties helped me, along with wool socks, but I was still suffering from chilled feet when I rode early Sunday morning. I think I'll put the plastic bags over my socks before putting on my shoes, then topping the shoes off w/my toe covers, then booties. I'll let you guys know if it helps.
