In reply to goosebump:
I have the male Monoliths, because of the extra room in the heel compared to some others. My Nepal Extremes and other sportivas are too tight/painful now, due to calcaneal/bursa growth at the back of the heel over the last few years.
As you know, with all boots the fit is EVERYTHING, and you can jiggle everything else to work. I've been out and about here is Scotland the last month with the Monoliths and they don't seem cold. I mean it isn't THAT cold here in winters, and you are generally only out on day trips anyway.
So if they fit well, and your toes aren't really hammered in there, I'm sure you will be happy with them.
A question for you:
My girl is currently sampling some Monoliths for herself, but up here we can only get the male version size UK 7. At that size she finds them a bit roomy up in the forefoot, not snug like a Trango, or like you're suggesting. Did you get the chance to try a male vs female Monolith, and can you report any reduction in forefoot volume by going to the female version? If so, it might be worth us trying to mail order some female versions.
Cheers
Bruce
