New for the 2025/26 season K2 is popping out with a brand new household of ski boots named the Cortex Assortment—sliding completely into K2’s catalog as a low-volume true alpine ski boot. This can be a model of boot that K2 has not provided in just a few years—the closest cousin in K2’s boot line-up being the Mindbender Assortment, which is a low-volume hybrid boot that’s good for the skier who desires to spend time within the backcountry and the resort.
The Cortex, alternatively, is actually designed for alpine skiers. The primary distinction right here is that the Mindbender line encompasses a stroll mode and the Cortex line encompasses a mounted backbone. This mounted backbone lends to improved downhill efficiency and a greater feeling of flex.
The K2 Cortex Line may even be K2’s first boot to characteristic a twin BOA closure system. For the previous few years, we have now seen a BOA dial used to safe the decrease shell of a conventional 4-buckle boot. Nonetheless, for 25/26 a BOA dial has been added to the cuff, changing what would usually be the higher two buckles. This newly added BOA match system pulls equal power by way of two impartial anchor factors, situated the place you’ll discover buckle anchors. This enables customers to twist a BOA and apply equal power to the 2 anchor factors, successfully producing a extra constant and comfortable wrap across the calf than conventional buckles.
Final month we took the Cortex 140 Zonal Boa boot out on snow to see how K2’s newly designed boot and its twin BOA system carried out. Try our ideas within the video under:
