I have mounted my new blades and used the same spot as my old ones because that was a perfect location for the blade. But my concern is that the new blades do not sit perfectly flush against the sole. It's like the toe plate is too long for the boot. The heel plate won't sit flush against the sole either. The old screw holes are perfectly flush with the sole leather and can't feel where they used to be. When I screw the new blades down as far as they will go, the heel plate doesn't sit flush with the heel of the sole. I read that this can cause the blade to warp/twist. The heel plate is about a millimeter off the sole in one spot. What should I do?
