I've used toe clips for going on 40 years. I wear them ever so slightly loose (less than snug) as my feet will feel a numb inducing pinch after a couple hours. That magic setting also makes them easy to shed in an emergency but snug enough to not slip pedaling. Been in a few wrecks and never felt trapped in them. I roll with SPD's on my mountain bike, toe clips on the Moto B and early 90's Times clipless on the Colnago. The Times are a flamimg B to get out of...non-adjustable and they have to be clean and waxed to work right...some day soon the Times will be C @ V (if they aren't already).
