The 2018/2019 K2 B.F.C. 120 was tested in the men's On-Off Area wide category at Silver Mountain Resort by the experts at America's Best Bootfitters, powered by Masterfit.

The Gist

Testers said again at this year's boot test (where it was the highest ranked boot in the men's wide hike mode group) that the 2019 K2 B.F.C. 120 isn't just Built For Comfort, it's built to house the most massive meat-dogs ever to maraud the slopes (and tailgate parties, base lodge apres, ski school kid hauls, etc)! Mega volume in both the lower boot and upper cuff and a solid 120 flex provides the sort of room and support the highest of volume human has been waiting for plus the convenience of an easy to use and functional walk mode.

The Fit

One tester summed up the B.F.C.'s overall fit this way: Soooo huge! However, he went on to say that the fit seemed congruent and well-shaped for the thickest of feet and legs (a sentiment echoed by other testers as well). And then he then pondered whether there are actually feet this big. We know there are, and we know that some folks simply don't like tight fitting footwear of any sort—and as such, this boot will appeal to fans of Uggs, Crocs and flip-flops.


The stance is upright for those with average calf volume—a larger calf will push the lower leg more forward and be just right, our testers guessed. The 120 flex is a bit overstated, testers reported, and they wondered if it would be enough support for the XXXL dude attached to such a foot. However, those who had tested the 90-flex two tests prior said this was still a big improvement, performance-wise. Generally, testers all agreed that the B.F.C. 120 was strong enough and quick enough for just about any decent skier with as balanced a lateral stance as one could want. Performance scores exceeded testers' expectations on this one.

Cool Features

The Apres Mode (that's what K2 calls it) walk feature is adopted from the other more serious hikers in the K2 boot line, but if nothing else, K2 knows its target customer. This cuff release mechanism is all about strolling parking lots, tailgating, beers at lunch (maybe breakfast too), and its ease of use and range of motion is fantastic, testers said. GripWalk soles can be purchased to make the strolling even more sublime (if you have an appropriate GripWalk binding). The B.F.C. 120's Convenience, Warmth & Features score was a perfect 5.0.

  • “Big everywhere: large foot and a high volume calf fit. Super roomy--big footers will love it. It's a warm couch wrapped around my foot, with a down blanket! Easy rider—has great feel for the snow and steering is surprisingly predictable. You've probably figured out the walk mode is for walking around, not ski touring--duh.” -- Kevin Gabriel
  • “Cavernous! I can hear my echo in here! You can fit a lot of skier in these! Kind of a chunky fit but then again, it's built for chunky—and I mean this in a very good way! Its power and energy was a surprise for me--performance mukluks!” -- Marc Stewart
  • “Massivemo! A hike mode on a boat--supermassivemo! For the huge of hoof, the fit is just fine. Edge power and quickness is right-on for the target, and convenience and warmth are epic (as are the proportions).” -- Mark Elling


  • “A little more upright for my taste but I'm sure it would be perfect for someone with calves bigger than my chicken sticks.” -- Marc Stewart
  • “A little soft for 120, but power is still decent.” -- Kevin Gabriel
