I wore mine around the house for a while and bent my ankles in them, e.g. doing dips, shoot the ducks, to try and crease the leather slightly.
Some people say that you should and shouldn't walk around in your skates, but it certainly worked for me.
What new skates did you get?
I recently broke in a pair of risport RF4's and they were soooo painful, I had red raw blisters from skating in them a couple of times, so I put little kitchen scrubbing sponges (cut off the scrubbing bit) in my boots to ease the pressure, it worked
Also if the boots are narrow at the toes, wear thin socks, like nylon ones (not cotton or thick socks, trust me) plus this helps the boots shape to your feet better.
Apparently it takes approximately 10 skating sessions to break the new skates in and to adjust to them, I presume you'll be adjusting to a new blade too :/
It's a good idea to just lace up to the third hook for the first few times skating in them, it allows more of an ankle bend, but you will eventually have to tie the fourth hook (my coach said the sooner the better) when you do eventually tie it, don't tie it as tight as the other hooks, leave it loose but not completely loose, means you'll be able to bend easier
Don't be scared to skate in them, yes it feels weird but for the first few times just do stroking and edges - try crossovers, glides, 3 turns etc.
Then try your jumps and spins.
I love my new skates, DON'T be tempted to go back to your old ones if the first few times skating doesn't go well, trust me after they're broken in they'll be your new best friend
Have fun. And remember to have bandaids handy for the blisters..ouch
