Head Kaliber Pro 120 LV GW BOA
The Head Kaliber Pro 120 LV GW BOA is a high-performance ski boot inspired by HEAD's race collection, combining race-level precision, the advanced BOA® Fit System and outstanding all-day comfort. It has been developed for experienced skiers who demand direct power transmission, exceptional ski control and race-inspired technologies in a slightly more forgiving package than the brand's stiffest competition models. With its narrow 98 mm last, adjustable 130/120 flex and Form Fit technology, the boot delivers an exceptionally precise fit, excellent stability and complete confidence during aggressive skiing.
The construction features a lightweight yet rigid polyurethane (PU) shell, Graphene reinforcement for increased torsional stiffness, a customisable Liquid Fit liner and a GripWalk® sole that significantly improves walking comfort away from the slopes. The BOA® Fit System works together with two micro-adjustable alloy buckles to provide fast, highly accurate adjustment and secure foot retention.
Who are they for
The Head Kaliber Pro 120 LV GW BOA is designed for advanced performance skiers, ski instructors and ambitious amateur racers looking to benefit from race-derived technologies while enjoying greater comfort throughout a full day on the mountain.
Its 98 mm last belongs to the Low Volume (LV) category, making the boot ideal for skiers with narrow to medium-width feet. The anatomical fit minimises foot movement inside the shell, providing superior precision and improved ski control.
The adjustable 130/120 flex delivers strong support for dynamic skiing while remaining slightly more forgiving than the stiffest race boots in the HEAD lineup.
Ideal for:
- Advanced performance skiers
- Ski instructors
- Amateur racers
- Advanced carving enthusiasts
- Skiers with narrow feet
- Demanding skiers seeking race-inspired precision and comfort
How they perform on the slopes
The Kaliber Pro 120 LV GW BOA delivers exceptionally fast response, precise edge control and excellent stability during aggressive piste skiing. Thanks to the narrow shell, Graphene reinforcement and Bi-Injection Construction, power is transferred directly to the ski edges for highly accurate turn initiation and control.
On hard-packed groomed slopes the boot provides outstanding support, confidence at higher speeds and excellent edge precision. The Bi-Injection shell construction optimises flex progression, producing a smooth yet highly responsive feel.
The BOA® Fit System, combined with two micro-adjustable alloy buckles, distributes pressure evenly across the foot, eliminates pressure points and provides outstanding foot retention.
Key on-snow advantages:
- Fast response
- Precise ski control
- Excellent stability
- Efficient power transmission
- Even foot wrapping
- Outstanding carving performance
