boots sizing problem

Alright, so I've never had the privilege of owning a pair of boots that actually fit me well. My shoe size is around a 9.5, but leaning more towards a 10. I just got in the 07 LF Sphynx boots I ordered in a size 9-10 and they feel a little too tight for me. Before I exchange them for the next size up, I pose this question: How exactly should bindings fit anyways? What should they feel like? Again, the ones I always end up with are either way too big or way too small. Comments on boot choice and proper size appreciated!

Usually out of the box they are going to be stiff and borderline uncomfortable. The material needs to be stretched out and this can only be done by wearing them and breaking them into your feet. A few sets of sacrificial foot pain often break a boot down to optimal comfort level. Get em in some hot water, walk around and work em in like a new baseball glove.

Alright. I just want to be sure I don't need the next size up (a lot of money)

Sorry for the hijack, but maybe this will help andrew too. What do you guys do to heat fit them? I've heard put your feet in a tub with really hot water. Is that what you do? Or is there something else/more to it?
