Intro
Head recently announced their Kaliber MV all-mountain ski boot collection, which includes models with an all-new dual-BOA closure system, and we discussed the highlights of the announcement in our initial writeup.
Now that we have the new Kaliber 130 MV BOA2 in hand for long-term testing, we’re adding some of our measured specs and photos here. We’ll continue to test it (and the women’s Kaliber 105 W MV GW BOA2) going forward; if you’re a BLISTER+ member or you have our Digital Access Pass, you can already check out our initial on-snow impressions in our Flash Review of the Kaliber 130 MV BOA2.
What Head says about the new Kaliber 130 MV GW BOA2 boots:
“The Kaliber 130 MV GW BOA2 offers all-mountain skiers unparalleled precision and performance skiing, thanks to a new construction with an integrated BOA® Fit System. The BOA® Fit System featuring a dual dial configuration allows for microadjustments to optimize the wrap around the leg and foot. The bi-injected cuff and shell were engineered specifically for BOA®, featuring stiffer plastic in the back for power, with softer plastic and an angled overlap over the foot. The mid-volume 100mm last offers a more anatomical fit, while the newly-designed Synapse Pro liner has Graphene woven in to help regulate temperature.
The BOA® Alpine dual-dial configuration delivers a micro-adjustable, multi-directional, zonal precision fit that locks in the heel to deliver superior power transfer, stability, and control. BOA® is engineered and guaranteed to perform.
The new SYNAPSE PRO liner is thinner and more anatomical, the Graphene woven in is a revolution in temperature regulation, keeping you warm, or cool, as needed.
The LIQUID FIT material provides the most precise and the quickest customization. The material’s density ensures the perfect mold in the most critical area of the boot, the ankle and heel pocket. It gives you the performance and precision of a foam liner, but as a liquid material, it takes only 10 easy minutes to customize. PLEASE NOTE: A Liquid Fit ready boot must be customized at your local authorized dealer.”

Weight (and Comparisons)
Our 25/26 Kaliber 130 MV BOA2 weighs about 2135 grams per boot for a size 26.5. That puts it on the heavier end of the spectrum for fixed-cuff alpine boots, but there are several comparable boots that have similar or heavier weights.
