Okay, finally got to visit the pro shop, I was remeasured (to confirm my length in Jackson’s was correct, which it was) and tried on some Ripsort too, the ripsort boots felt pretty good (maybe a bit better than Jacksons but without actually skating it would be hard to tell) and they might be able to hold my heel/ankle better if I laced them tightly but it would still be a gamble. Other than that I was told to look into getting extra padding or gel in the area so my ankle can’t move, but I don’t think that’s a great long term solution. I was also told I probably won’t need new boots soon (wasn’t asked about my weight or size though and also the person telling me this was a hockey skater). Other than potentially switching brands or extra padding no other solutions were presented. Unfortunately one of my parents is of the opinion that I’m being melodramatic about the whole thing and that the heel/ankle moving even with pretty tight lacing isn’t a concern or potential safety issue. I literally had to waste the first 20 minutes of my practice session today because I had to go re-tighten my boots (with high effort in tightening) just so my foot wouldn’t move. Sorry about the mild rant. On a more positive note though, my spins have improved a lot, so that’s good I guess.
