I've had PowerGrips on my bikes for years. I like platform pedals, and I like to wear whatever shoes I have on. Sometimes, proper cycling shoes, too.
I was an early adopter of PowerGrips, and still like 'em. Not all pedals can mount them. They need the eyelets on the back side of the pedal, too.
I'm still a non-adopter of clip-ins. YMMV.
