I find I like riding clipless since most of the time the roads are clear, but I'm getting cold with my toe covers and find the PI Toasters to be a PITA to work with. My boots are warm, but I keep lifting my foot off the cage on the upstroke and my foot slips off the pedal. (I guess those powercrank things really do train you to lift up). Anyway, I got my Nashbar catalog and what do I see but 2 winter riding shoes that are SPD compatible (of course neither are in stock in my size at Nasbhar, but I can find them elsewhere). I guess I want to know from people who have used them. How do the Lake and the SIDI compare to each other, and how do they compare to a lightly insulated winter boot? How about walking in them? Anyone use them and like/dislike them? Thanks for the input.
