if they fit perfect, that's all that matters. they're really good boots by the way, the booster strap is awesome on those boots. however, i've had a few people w/ those boots come into the shop after skiing them a little bit, saying they packed out quite a bit (which is expected) so you just might have to get them padded up a bit after some use. hope that helped, enjoy the boots homie.
yoo i have the speedmachine 8. they are extremely comfortable, and perform well. personally, i removed the built in booster strap and used my own booster strap, but since urs are 10 they probably hve a better booster anyways.
my shins still hurt in them,, but my shins are sooo effed up that it says nothing about how good this boot is.
