I'm a long distance tourer, and used toeclips and straps happily for years.
Last year I decided to pick up a set of Candy Eggbeater clipless; I practised getting in and out, rode for a few months and loved them. Then I rolled it twice, once almost under traffic, due to being unable to release in very sudden stops, scared the crap outta myself and went back to the straps.

Now I'm determined to try the clipless again, and I've sat down and analyzed my release problems- the problem is at the top of the spin, I can't get enough angle to release. My knees/ankles just won't bend out that far. At the bottom of the spin no problem.
And of course in an emergency stop I have no choice of where my feet are when I have to try to pull out, and no time to think about it- one of them is most likely to be at the top of the rotation.
I've checked very carefully to make sure the Candy cleats are in the 15degree outward release position, (double-dotted cleat on right foot) and even angled the cleats as far as possible to 'cheat' it a bit.
Is it possible that it's just my knee/ankle alignment?
My feet certainly seem to be pointing straight foward- (at least that's the direction I always seem to travel when I start walking...)

Anyone else with this problem? Any suggestions? Or should I just stop whining, get back out there and practise my kayak-style bike rolls?

Cheers
