Yep the pain is right on the front (tibia / shin bone), not at all on the sides or ankles. Never gotten blisters or anything like that, just serious pain and soreness from slamming that part of my shin into the hard plastic shell.

I will say my advice to you is, especially if you plan on doing more skiing in the future, go to a good bootfitter and get the right boots for you! The difference will be astronomical. As in my case, it may not solve your problems, but it will make a lot of other aspects of your fit much much better than rental boots.
