I have regular Speedplays on my road bike shoes, lots of float, nice click sound and feel when I clip in. I now have MTB shoes with Frogs that I bought for my America by Bicycle tour (will report later) this July. My DH had to carve out a bit of my MTB shoes to set the cleats to get enough "toe out" float for my knees, and this worked out fine. I do find it a mystery how and when I clip into the pedals. No consistent "click" or feel of being engaged in the pedal until I pull up on the pedal to check if I am clipped in or not. But yes, they are insanely easy to get out of! And walking on the MTB shoes (specializd Moto Divas) was a real pleasure for touring. Tokie
