Black Diamond Quadrant

Some relationships define themselves immediately. Others refuse easy explanation. That's about where I find myself with Black Diamond's stubbornly-ambiguous Quadrant A/T ski boot. In terms of niche the Quadrant competes directly with Garmont's excellent Radium, seeking to offer high performance at a tour-competitive weight. It's easy to quantify the Quadrant's weight—seven pounds, four ounces per pair (more...)

In the stats at the beginning the weight is incorrect, I think. My eyes certainly popped out of my head when I read that 4.49lbs/pair, though, and I was disappointed to find out it was wrong.

I bought a pair of quadrants, but I knew I was going to be throwing away the liners. The achilles pad things are insane. I have a normal-narrow foot - my d/h boots are langer blasters - and the achilles pads pushed my foot way too far forward. Couldnt understand what was going on until we pulled the liner out, pushed in a scarpa liner and the fit was suddenly spot on. Dunno why BD do this. Awesome boot - bought to replace a 5 year old pair or adrenalines for touring...and may well replace my langes too. very pleased with the end result but still think that BD would sell a ton more of these if they made normal liners.
