In reply to fire_munki: I use Scarpa phantom guides which I really like. I'm sure you know what makes a good boot so I'll not bother going into detail.
I've got a pair of the Scarpa Charmoz and had a pair of manta's which aren't as warm as the PG's but just as comfortable.
If you really want warm feet or climb in high or cold places it could be worth looking at the Phantom 6000 which is a double boot with built on gaiter.
