In reply to keith leonard:
I find this the same with the Atomic Backland Carbons. Tried the Salomon MTN Explores and they are much warmer, but also heavier and definitely focused on downhill rather than skinning/climbing. The Backland Carbons felt very similar to the Proclines but slightly better suited for downhill (and for my fat feet), I've read that adding one of the thick warm Intuition liners solves the cold-feet problem as well as providing substantially better calf support.
It's a (currently) inevitable drawback of having incredibly lightweight flexible boots, the materials to achieve the spec are just terrible insulators. Swapping out the liner for something heavy-duty and using an ultra-thin merino liner under your boot sock is the only alternative. Just watch the sizing when moving to a thicker liner.
