The K2 Cortex 105 Zonal BOA ski boots redefine performance and comfort standards thanks to an innovative design. Designed for advanced to expert skiers, they combine micro-adjustable precision, fast response and personalized fit.

Dual BOA technology: precise, balanced fit

The Dual BOA® system on the K2 Cortex 105 provides optimal control over the collar and shell. Adjustment is facilitated by even pressure distribution around the leg, improving flex and response while reducing pressure points. No more long minutes searching for the perfect fit: the BOA system lets you get started quickly and confidently.

Personalized fit and maximum comfort

Inside the shoe, the EliteFit Sport liner features integrated laces and an adjustable tongue, guaranteeing optimal comfort even on long days on the slopes. The TPU shell and collar offer added strength and lightness. Thanks to FastFIT Instep technology, putting on and taking off the boots is quick and easy.

With a flex of 105, these boots are perfect for experienced skiers looking for precision and responsiveness. For even more customization, K2 Cortex 105 boots feature an adjustable rear spoiler and a double collar alignment system.
