Was very satisfied using Shimano M520 SPD pedals with
Nike Kato MTB shoes for a few years on my roadbike:

When my Nike shoes wore out; I decided to try "road" pedals. A fellow club rider gave me his used Look Keo's. They felt nice
with an old pair of SIDI's I had; nylon soles. But I just couldn't get used to the single sided pedals. I was so used to the double
sided SPD where I just stomped on the pedal and go. W/ the Look's, I was always missing the top and was constantly flipping
it every time the light changed green. I got rid of them and tried Speedplay's. Double sided just like SPD; I'm a happy camper
