If you're THAT hard core a skier
, I can tell you how to self-test your bindings...
Step into both skis and stand on a flat spot on the snow with your feet about shoulder-width apart. Putting most of your weight on the inside ball of one foot and leaning slightly forward, drive that big toe OUT of the toe binding by twisting sideways. If you can't do that without hurting yourself, the toe setting is too tight. If you can do it fairly easily but you're never releasing on the hill, then congratulations.
To test the heel setting, stand (feet hip-width apart) with one ski on and one ski off. Start with your boot foot (not the ski foot) a small step behind. Step slightly forward with the boot foot and as that foot is planted, drive the knee of your ski foot straight down toward the front of the ski. If your heel binding is set properly, you should pop right out of it. Again, if you come out without hurting yourself and you haven't been releasing on the hill, your setting is good.
WARNING: Only a really good skier who never falls can do this without injury.disclaimer: while I'm nowhere near good enough to never fall, I do this two or three times a year with all my skis. It's a totally legitimate way to test your own bindings and settings.
