So since I can get no input from my "trainer" (lol), can someone tell me if these bell boots look like they fit? I felt like they might be a bit big (at the top I can fit almost 1-2 fingers), but I also feel like a medium might be too small.

I am no expert, but it would be better to have those looser rather than tighter because they will rub.

I would agree that you wouldn't want them too tight, but maybe this will help with sizing:

As long as they won’t fall off and they protect the back of the hooves then I think they’ll be ok, but if they wiggle around too much when moving you might want to try a medium anyway. I’m not an expert though so I could be wrong XD
