2026 K2 Anthem 105 BOA Women's Ski Boots

With a mid-volume fit and a 105-flex rating, the K2 Anthem 105 BOA ski boots are fantastic options for intermediate through expert skiers who are looking for all-mountain versatility and all-day comfort. There’s a lot of innovation here in these boots, and it all starts with the BOA closure system and the lighter weight overall feel.

Why we like it:

We love the combination of fit and performance here. The 105-flex pairs great with the 100 mm forefoot last and mid-volume fit to appeal to a very broad audience. With boots, it’s hard to make something that is so widely appreciated, and this Anthem 105 BOA fits that description quite well.

Who it's for:

Strong skiers will get the most out of this Anthem 105 BOA. With the new closure system, you can fine-tune and micro-adjust the fit in the forefoot to make you feel more connected to the ski. There are a lot of features and benefits to this boot that will appeal to an advanced skier who is looking for refinement and sophistication in their boots

Highlights:

We’ll start with the BOA closure system as that’s the most obvious—this has worked great in K2 boots so far. We also get a non-elastic cam strap to cinch up the top of the boot, a modular honeycomb boot board with hard and soft inserts, dual adjustable cuff alignment, and a fully heat-0moldable shell and liner. Every piece of this boot has been well-thought out and crafted to blend fit and performance.

Things to consider:

BOA is new, so maybe a bit of a learning curve for some.

Fit & sizing considerations:

The closure system allows for a shrinking of the forefoot last, so narrower feet will have good success in this mid-volume width.
