I guess I am the complete reverse - I've been riding with Frogs for about 7 years, love them.

I started doing spin class back in Oct, and have gone 2x week from Oct through the end of May, using SPDs. And after 8 months I STILL can't clip out on those things. If I ever got on a real bike with those pedals I'd have fallen every time.

They look to be identical, but I'm starting to wonder if the cleats on my spin shoes are reversed L/R because I can unclip not by turning my heel outward, but can if I turn my heels inward.
