One simple innovation made Dynafit's new AT boot a trendsetter this season – the top buckle engages the aggressive ski mode when snapped shut and automatically puts the boot in comfy walk mode when opened. Beyond that, the burly boot features a responsive cuff, but it's amazingly light at just 1,650 grams. That construction imparts the ability to charge like a standard alpine boot on the downhills, but it doesn't slow you down huffing up the skin track. [$1,000;]
