I have the BMX style platform pedals with the little pins sticking out of them. As long as I'm wearing a shoe with a soft sole at least 1/4" thick, the studs dig in and give me almost as good a grip as SPDs. What I like about them is that I can wear hiking boots in the winter, which are much warmer than any cycling shoe I've ever seen. And of course, I can walk places on my lunch hour in the same shoes or boots - no need to keep an extra pair under my desk just for that purpose.
