I think most of the time this is caused by 2 things: the skate being too tall in the ankle cuff, combined with the curvature of your leg (think bow legged). Ski boots, which come up high on the leg, have an adjustment to change this angle called canting adjustment. Unfortunately, skates do not. The only way I've found to take care of this problem is to rebake the skate, take a pair of pliers or similar to manually bend the cuff away from ankle (you can cover boot cuff with a towel as to not damage the skate). It only needs to be moved a couple mm.
