True, in my experience, but ...

but ... having an extra pair of thick wool socks (and generous room in the shoes for them) can be really valuable to avoid this pressure problem. So upsize by half a size, whatever you wear.
I know on one trip I wore two pairs of Darn Tough Vermont boot socks and had no problems with pressure, while Sue wore just one pair and complained about the pressure and rubbing. Same shoes, same snowshoes.
It can actually be just the time to go with some GTX shoes if there is a chance you may not be wearing the overshoes al the time. Yes, GTX plus overshoes is overkill, but the extra flexibility is valuable.
I wouldn't use the VBL unless it was really cold. And I would not aim to keep my feet hot, or even really warm. Just comfortable is best to reduce sweating.
