The Head Kaliber Pro 110 LV GW BOA2 is a high-performance ski boot inspired by HEAD's race collection, combining exceptional precision, the advanced Dual BOA® closure system and all-day comfort. It has been developed for experienced skiers who want race-derived technologies for dynamic piste skiing while maintaining the comfort needed for long days on the mountain. With its narrow 98 mm last, adjustable 120/110 flex and Form Fit customisation, the boot delivers excellent support, an accurate fit and highly efficient power transfer.
The construction features a lightweight yet rigid polyurethane (PU) shell, Graphene technology for increased torsional stiffness and a GripWalk® sole that significantly improves walking comfort away from the slopes. The innovative Dual BOA® system provides more even shell closure and a more precise fit than traditional buckle systems.
Who are they for
The Head Kaliber Pro 110 LV GW BOA2 is designed for advanced recreational skiers, instructors and ambitious amateur racers looking for a precise performance boot equipped with the latest fitting technology. Combining All Mountain versatility with Race-inspired performance, it offers outstanding control on groomed pistes while remaining comfortable throughout the day.
The 98 mm last belongs to the Low Volume (LV) category, making the boot ideal for skiers with narrow to medium-width feet. The close anatomical fit minimises foot movement inside the shell, resulting in more accurate ski control and more efficient energy transfer.
Its adjustable 120/110 flex provides strong support for aggressive skiing while remaining slightly more forgiving than top-level race boots.
Ideal for:
How they perform on the slopes
The Kaliber Pro 110 LV GW BOA2 delivers fast response, highly precise ski control and excellent stability during dynamic skiing. Thanks to the narrow shell, Graphene reinforcement and Bi-Injection Construction, energy is transferred efficiently to the ski edges, making every turn more accurate and controlled.
The Dual BOA® system distributes pressure evenly across the lower shell while eliminating pressure points. This provides greater comfort, improved foot retention and more precise ski control throughout the day.
On hard-packed groomed pistes the boot offers excellent stability, strong support and highly accurate edge control. Its performance-oriented flex remains comfortable enough for extended skiing sessions.
Key on-snow advantages:
Understanding the specifications
Flex 120 / 110
Flex determines the stiffness of the ski boot. A flex rating of 120 provides excellent support for aggressive piste skiing, while Flex Tuning allows the stiffness to be reduced to 110 for smoother flex progression and increased comfort during longer ski days.
Recommended for:
98 mm Last (Low Volume)
A 98 mm last provides a narrow performance fit designed for precise foot retention.
Benefits:
GripWalk®
The GripWalk® sole improves walking comfort while offering better grip on hard and slippery surfaces, remaining fully compatible with GripWalk bindings.
Benefits:
Dual BOA®
The Dual BOA® closure system uses two precision dials to tighten the shell evenly around the foot. Compared with traditional buckles, pressure is distributed more uniformly for increased comfort and better performance.
Benefits:
