Bought some Skates at Canadian Tire for my sister's birthday. They're the right size, but they hurt her ankles?

It's because the skates are not broken in, i've been a competive figure skater since I was 8 and now im 16 and I know how it is to wear new skates! It hurts so much, its because your feet are not used to them yet, what my coach suggests to me is to tie them up really tightly and just sit around and watch tv in them and let your feet and ankles get used to them, also if you have guards walk around the house with them on. Or you could put a hairdryer inside the skate and heat them up then tie them up really quickly to mold them to your feet. Or you could get them professionally molded.
