You dont need the worlds best bootfitter to try on boots. He can try them on to see if they are remotely close to the shape of his foot. Just trying on a boot is better than taking a guess and buying from a kid off the internet.
And the booters will loosen even more because the hotdoggers have the pro liner which tends to not pack out as much, vs the booters have like the normal liner or something (not sure the name) and they pack out more
if you don't have a good bootfitter near you, you shouldn't be skiing wherever it is you carry on your shitty life. you don't need booters to lean back and wear tight pants, go to sports authority and buy something comfy.
