I'm on the hunt for some new B2.5ish boots for winter climbing and one of my local shops is a Zamberlan stockist - they had a couple of models in which were pretty comfy, but there doesn't seem to be much information available about the stiffness rating for them, and the assistant was a bit vague about it. I've had a look at the Zamberlan site, which is equally vague about their product, and there doesn't seem to be much in the way of reviews available for them either.
The particular models I was eying up were the 3050 TORRE GT RR, and the 4041 EXPERT PRO GT RR - if anyone has any insight into their suitability, it'd be much appreciated.
