Fit/Comfort 
Out of the box, this one’s a winner. The custom-moldable foam liner, complete with faux-fur-lined cuffs, feels super plush—cozy, warm, forgiving on the ankles. There’s also plenty of space in the toebox without being sloppy. For a boot lacking individual dual-zone adjustments, the fit doesn’t suffer much; there are no pressure points on the instep or ankles, even when you’ve cranked down super hard on the single Boa.

Cushioning
The Haven is a relatively soft boot with plenty of cush underfoot for riding all day. If you spend a lot of time in the park, the shock absorption is on par with comparable all-mountain boots—nothing outstanding, but certainly enough to get the job done and leave your feet in good shape by the end of the day.

Responsiveness
The Haven’s overall softness and lack of a secondary Boa coil or other lacing system to separately snug down the instep can leave it a touch too flexible at times. While this boot performs exceptionally well on groomers, mild slopes and light powder, its responsiveness suffers some on steeper terrain, in deep powder, or while initiating tight turns in the trees.

Walkability
Because this is a comfortable boot overall without too much aggressive forward lean, it makes for easy walking when you’re on your way to or from the slopes. The tread underfoot performs admirably, even in icy parking lots or skating off the lift. It lends plenty of confidence on hike-to terrain as well.

Lacing System
If you ever need to win a contest in speediest donning and/or removal of snowboard boots, the K2 Haven is your ticket to success. With just a single Boa coil to adjust the outer laces and an easy pull-tab speedlace securing the liner, nothing could be simpler—even with frozen fingers or while wearing bulky snow gloves. The only downside of the single Boa is that there’s no way to individually adjust the upper and lower zones, limiting the customizability of the boot’s fit and leading to a bit more heel lift than in comparable models.
