Ditto for my Speedplay Frogs.
http://www.speedplay.com/index.cfm?fuseaction=home.frog No moving parts, passive release. Gotta love it in my little universe! I like showing off how easy they are to get in and out of by "clicking" my empty shoe in with a gentle 2-finger push, and "clicking" out by letting go of the shoe and letting it just untwist itself right off the pedal and fall off.
Thank you for clarifying what you were looking for, Laura.
Speedplay Frogs are ABSOLUTELY easier for me to get out of than toe clip/cages. I used cages for many years, and I was pretty darn good at managing them, but Speedplay Frogs had them beat all hollow within a couple weeks.
