K2 BFC 105 W BOA Ski Boots 2027 // Women's
Description
Bootfitter's Notes
The BFC 105 W BOA is one of our most popular women's boots for skiers who value comfort above all else. Built around a generous 103 mm last, it offers plenty of room through the forefoot, a comfortable amount of space over the instep, and a plush liner that feels great right out of the box.
The lower Shell BOA evenly wraps the forefoot and instep, improving foot hold while reducing pressure points compared to traditional lower buckles. Even with its comfort-oriented fit, the BFC 105 W provides enough support to confidently drive modern all-mountain skis. The flex is strong enough for advanced skiers but forgiving enough that progressing intermediates won't find it intimidating.
The heel and ankle are softer than many performance boots, but when you're in the correct size they provide more than enough retention to keep your foot secure without feeling restrictive. The shell is also one of the easiest on the market to modify, making it an excellent platform for skiers with bunions, pressure points, or other fit challenges.
One of the biggest highlights is the cuff. The BFC 105 W is incredibly accommodating around the lower leg and can fit some seriously large calves. If you've struggled to find a boot that comfortably wraps your calf, this is one of the first models we'd recommend trying. Even when additional room is needed, it's a boot that most experienced bootfitters can successfully adapt.
K2's integrated Après Mode adds another level of convenience, making it easy to walk around the lodge, parking lot, or après scene without feeling locked into a rigid ski boot.
If you have wider feet, larger calves, or simply want one of the most comfortable women's boots available without giving up dependable all-mountain performance, the BFC 105 W BOA should be at the top of your list.
TL;DR
Size Chart
Use the sizing chart below to get a general idea of your ski boot size, but keep in mind that personal shoe habits — like sizing up — can make charts misleading. Ski boots are sized in mondo point, which is simply the length of your foot in centimeters, and there’s no true half sizing — 26.0 and 26.5 are typically the same boot.
