Tried out the Shimano SPD shoes with the new dual platform pedals today on a short 15 mile ride and everything seems to work very well. The shoes are comfortable for riding (for which I bought them), not for tackling mountain trails. To the naysayers, I am pleased with my purchase and my setup. I set the release on the pedals at an easy clip-out setting starting off while I get used to clipping in and out. Later as I get more accustomed to them, I will probably make them a little more tight. Again, I am pleased that I bought road shoes, and not MTB footwear. BTW, the adaptor works well with the shoes to make them "recessed".
