Head Kaliber 105 MV GW BOA2 - Ski Boots

Ski Boots with Precision and Maximum Control

The Head Kaliber 105 MV GW BOA² is a high-end ski boot for advanced and expert skiers who want a precise fit, stability, and efficient power transmission. The dual BOA® system allows independent, fine adjustment of the tightening around both the foot and the shin, without traditional metal buckles.

The innovative two-plastic construction provides a stiff support zone for better energy transfer and a softer zone over the instep for comfort and an even wrap around the foot.

It is a great choice for skiers who want high precision, powerful power transmission, and individual adjustment of the fit.
