Description

With its 98 mm Low Volume fit and flex rated at 85, the K2 Cortex 85 Boa W provides precise hold and efficient power transmission for skiers who start their day on groomed slopes before venturing onto the edges, into powder, or through more rugged terrain. The BOA system enables quick tightening of the shell around the instep.

What is the intended use of the K2 Cortex 85 Boa W ski boot?

This boot is designed for both piste and light off-piste skiing, featuring a flex rating of 85 that absorbs snow variations without compromising responsiveness. The BOA system tightens the shell with a single dial, saving time. The Energy Bolt spine provides solid rear support and precise forward flex, with a removable upper bolt that softens the cuff rebound when taken out. The 98 mm last suits narrow feet, offering a snug fit for direct edge control.

Who is the K2 Cortex 85 Boa W ski boot for?

The Cortex 85 Boa W is ideal for intermediate to advanced female skiers with narrow feet who like to alternate between groomed runs and fresh snow along the edges, without committing to an overly stiff flex.

What are the main strengths of the K2 Cortex 85 Boa W ski boot?

Versatility

Precision

Freedom


Is the fit suitable for narrow feet?

Yes, the 98 mm True LV Fit is tailored for narrow feet, ensuring a precise fit that transfers pressure directly to the ski edges.

How does the Energy Bolt Spine work?

A screwed rear cuff provides strong rearward support and accurate forward flex. The upper bolt can be removed to achieve a more progressive cuff response and a smoother rebound.

Is the liner heat-mouldable?

Yes, the EliteFit Plus liner is heat-mouldable and conforms to the shape of the foot after heating or a few sessions on the slopes.

What is the difference between the K2 Cortex 85 Boa W and the K2 Anthem 85 Boa?

The Anthem 85 Boa shares the same 85 flex but is designed purely for piste skiing, with a more generous 100 mm last. The Cortex 85 Boa W, on the other hand, allows to dabble in freeriding with a narrower 98 mm LV fit and an Energy Bolt spine that enhances rear support for exploring fresh snow.
