Since the Mirage was more of a beginner blade than the Coronation Ace, it may well be harder to avoid the toe pick on the new blades...
I will send you my link on making the inside of your boots fit you, using tape, foam, and/or modified insoles.
However, if your boots are too long, or your toes too short, it is quite possible that your foot isn't able to bend well at the point that the boot tries to bend the toe area upwards. I wonder if that could cause shin pain? To some extent, if there is room enough inside, especially if you remove the old insoles, you can put in your own custom insole that bends your foot where it needs to bend, at the ball of your foot.
It is barely possible that problem could also create a toe pick scrape - because your foot doesn't bend enough, the front of the skate MIGHT be forced down. Same solution.
It is also possible that you need to change your foot orientation, pulling the front of the foot back, or that you or leaning forwards as you skate. Most beginning figure skaters are better off more upright, with a bit more weight on the back of the foot than the front while skating forwards. Because of that EVIL toe pick, leaning forwards doesn't work very well in figure skates. But a good coach would be able to figure those things out.
Such fast progress! I'm so jealous! Do you have experience in dance or gymnastics?
