The SnowSports Industries America (SIA) SnowShow in Denver is a global gathering of snowsport's best brands, athletes, and business leaders touting next season's hottest new gear and innovations. Here's what you need to know about the new materials making ski boots more comfy than ever.

Mr. Luxury Ski

Boots are doing what they can to keep up with the weight and material advancements in skis, with manufacturers racing to develop the ultimate in comfort and performance.

K2 Spyne 120 Heat.

K2 Spyne 120 Heat.

The K2 Spyne 120 Heat (above) isn’t the first boot with a built-in heating system. But it is the first that isn't limited to the frontside. Indeed, with 120 flex rating, this boot has everything you’d expect in a pro model even while it wraps your footsies in warmth, sole to calf; heating lasts up to 19 hour on one six-hour charge.

What’s in a name? Known for their stiff, hard charging boots, Nordica steps up to demand for walkable-hikable ski boots with their new Strider lineup. An ultra-light cuff construction cuts weight without sacrificing steering power and strength; open it up for plenty of room to hiking or lock it down for optimum energy drive for the downhill performance you expect in a Nordica boot.

In case you missed it, Easy in, easy out three-piece ski boots are back, baby. The classic design is mastered in Full Tilt Boots' New Tom Wallisch Pro (above), a flexy fit with Intuition heat-mold liner and extra shock absorption for landing big hits. If you’re looking for something a bit more stiff, step into the First Chair 10.
