K2 Cortex JR BOA® Junior Ski Boots

K2 Cortex JR BOA® are advanced ski boots for young skiers who want to ride equipment inspired by adult models. Equipped with the BOA® Fit System, they provide fast, precise adjustment without the need to adjust multiple buckles, making it easier to get ready to ski and focus on improving technique.

The TPU shell and junior-specific boot construction offer the stiffness and precision needed for dynamic skiing on and off the piste. The narrow Low Volume MultiFit Last (96–98 mm) provides a secure foot hold, while full heat-moldability allows the boot to be perfectly adapted to individual anatomy.

The BOA® Fit System enables micro-adjustment with a single dial, evenly wrapping the foot and increasing comfort and control while skiing. In addition, FastFit Instep technology makes the boots quick and easy to put on and take off, which both young skiers and parents will appreciate.

All-day comfort is provided by the EliteFit Plus liner, made from soft foams with a more comfortable profile that provide warmth, comfort and a good fit. The construction is complemented by a 30 mm Velcro Strap, which increases cuff stability, and GripWalk® outsoles, which improve grip and comfort when walking.
