Forgot to mention I use Look cleats, and Shimano pedals (600). There's also a tension adjustment screw on every pedal--so between having the cleat tight, the tension can be adjusted to make it easier or harder to get out of (didn't see that mentioned in prior posts). But if you had to twist your ankle around more than 15-20 degrees, check the fit of the cleat to the shoe! (but sounds like the pedal change has helped you, hooray!)
