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.
