I had a thread on this not too long ago:

I like them a lot for fixed gear riding. There isn't enough pedal purchase in street shoes to safely ride fast/far without clipless shoes, but for running down to the LLS with my 42x16 they are fine with street shoes. Skidding and all that is a lot easier with the additional platform as compared with my regular eggbeaters.
