I've noticed this with the boots I've had the past 3 yrs: NBx686, Burton Ion, and Burton Imperial. I think because they try to make the boot so low-profile, lightweight, and minimal, it results in very little material on the upper part. Without the additional padding or whatever you're used to, you feel the straps more when you really crank them down. Looking at something with a really bulky upper like the Vans Aura, I would imagine it would be much less noticeable with those.
