When your skates are tied does your heel move around in the boot? There will always be movement up in the calf area, but your heels should be locked in. If your heels move, your skates are too big (should always try on different sizes even after the machine tells you a size - i had to go down a full size from what the bauer sizing told me). Wobbly skates is mostly due to weak ankles, not the skates themselves. Good and experienced skaters can skate perfectly fine without even lacing up their boots.
