I remember now what I came back in here for: to report on my first commute (and first ever ride ride) with cleats. Quite different to toe clips; much more direct; quite a lot more shock comes back up from the road, which is probably due to fixed gear; need to put the saddle up a bit. I'm not sure if I'm sold for commuting. The feel of the bike is different and it all feels a bit serious. Having to flick the pedal over was harder as well and not easy to pedal if you miss. I can't now jump off and nip into the shops, or jump on it at lunchtime to go get last minute lunch for that matter, so they might stay off the bike for use on Sunday bests and racing.
Look Keos with 4.5 degrees float. If I got them again I'd probably get the zero float option for a more positive foot location. For what I use my bike for, a shoe with concealed SPDs and pedals with a flat on one side would probably be better but still not as flexible for me as toeclips.
