How do you get used to new skates?

I’ve taken a break from skating, I just haven’t had the time to go anymore. Anyways, I’m a size 8 in normal shoe size, but my skates are size 8 and they’re hard to get into. So I was thinking of buying new skates and the last time I bought new ones, they were so hard to get used to! I couldn’t break, skate steadily, do spins, etc. I don’t want that to happen again. I need to get used to them quickly so I can get started on private lessons. Or I wonder if the skate shops could stretch the skates out for you….
