bone unwanted rotation

I have an armature set up with constraints to keep the shin bones from rotating, but when I try to move them the shin bones move up and to the left. I double-checked the position of each bone and they themselves are not skewed, I wonder why it’s messed up. If you need the blend file to look at it I’ll give it via PM. Here’s a picture to help explain it. When at rest, the feet are perfectly symmetrical.

I’ll take that blend file. [email protected]

Turn on the axis display for the bones. You might find some are pointing in odd directions.

You’re right, the axis display shows a rather bent axis! Is there a way to fix the axis?
