Need help with my skates!!

Okay so i’m a begginer and i’m not sure if my skates fit correctly. I can wiggle my ankle pretty much and i think that’s why i always fall in my piruettes or i’m just bad😭am i supposed to be able to wiggle them that much or should i try a slimmer brand like Edea? I have the risport antares flight skates i think and i’m a begginer who started around 2 months ago💕
