I have really big feet and always felt uncomfortable with clips. I started using clipless with SPDs and really liked them but I had some problems accidentally pulling out during hard acceleration so I switch to eggbeaters. A couple of weeks ago I started using Look Keos knockoffs ($49 at Nashbar) and really like the stability and platform that wasn't there with the eggbeaters. There are two things I don't like about Look style pedals: poor walkability is one. The other is that I am accustom to unclipping when I don't like the road surface (like when you suddenly encounter gravel) and standing on the pedals with my arches so that I can still pedal but can get off fast if I lose the front wheel. I also do this if I am almost at a stop but want to roll forward an extra 20 feet but might at any time need to put a foot down. That works fine with a mountain shoe but I slip right off with the road shoes so this will require an entirely different technique.

I'll ride the Look-style pedals for a while but keep some eggbeaters on the winter bike and see how I feel at the end of next year.
