About Head Kaliber 105 W MV GW BOA2 – Ski boots

The Head Kaliber 105 W MV GW BOA2 is the ski boot for you who seek top-class performance, but at the same time want a fit that can be precisely adjusted to your foot. It is developed for advanced skiers and has a construction that provides both power and comfort – all day long.

This model is specifically designed to integrate the BOA® Fit System with dual adjustment dials. This means you can fine-tune the fit around both your leg and foot in a way that provides even enclosure and a secure feel, no matter how hard you push in turns.

The shell is built with dual plastic layers. Stiff plastic at the back provides stability and power transmission, while softer material over the foot makes the boot easy to put on and comfortable to wear. The last is 100 mm wide, providing a medium volume fit that suits many feet.

Inside is the new Synapse Pro liner, which is anatomically designed for women. It is reinforced with graphene, which helps maintain a consistent temperature – whether it's cold or warm. The liner is also prepared with Liquid Fit material that quickly adapts to the shape of the foot where it's most needed.

The Kaliber 105 W MV GW BOA2 is an obvious choice for female skiers who want precision, responsiveness, and comfort in every turn.

Fit & last

The last is the boot’s width across the ball of the foot. 100 mm is a medium width and suits most people. If you have a wide foot or high arches, we can spot-heat the shell in the store where it presses. The boot should feel snug when you try it on: your toes touch the front when you stand straight and pull back when you bend your knees. The liner packs out 3–5 mm during the first week, so a boot that feels comfortable in the store will be too big after a week. Always measure mondopoint — boot size has nothing to do with your normal shoe size.

Boot fitting

Buy your ski boots from us and you get free boot fitting for 1 year from purchase. That means we heat-mould the liner and grind or punch the shell at no extra charge. If we need to add materials or products, such as a custom-moulded footbed, you only pay for those — not for the work. You’re welcome to drop into our store at Isaberg, Sweden for up to 1 year after your order is placed.

Shipping & returns

Delivery time: 2–5 business days to Germany, from our warehouse in Hestra, Sweden. If the boot doesn’t fit right, free boot fitting is included for 1 year from purchase. Call +46 370 33 97 70 if you’re unsure before you order.

Choosing ski boots
Your ski boots affect your skiing more than any other piece of equipment — and they’re the hardest to choose online. Below we go through mondopoint, flex, last and what a boot fitting does.
Mondopoint — measure your foot, not your shoe size
Ski boots are sized in mondopoint, which is the length of your foot in centimetres. Stand with your heel against a wall, mark your longest toe and measure. That measurement is your size. Your EU shoe size is a poor starting point because it varies between manufacturers. A ski boot should feel snug when it’s new — the liner packs out 3–5 mm during the first week of skiing.
Flex and what the number means
Flex describes how much force it takes to bend the boot forward. 60–90 is soft and forgiving, 90–110 is an all-round level, 110–130 is stiff for skiers who ski hard, and above 130 is race level. The number isn’t standardised between manufacturers, so a 100 from one brand can feel like a 110 from another. If you’re heavy or ski aggressively, you want a stiffer boot; if you’re lighter or a beginner, you want a softer one.
Last — the width of your foot
The last is the boot’s width across the ball of the foot. Narrow is around 98 mm, medium around 100 mm and wide around 102 mm. A medium last suits most people. If you have a wide foot, a last that’s too narrow isn’t something you get used to — but the shell can be heat-moulded to make room where it’s needed.
Boot fitting makes the difference
Nine out of ten skiers have something adjusted at their first fitting. We analyse your foot, heat-mould the liner and grind or punch the shell where it pinches. A custom-moulded footbed gives better heel hold and less foot fatigue, and is the single biggest improvement you can make without changing boots. Buy your ski boots from us and free boot fitting is included (materials such as footbeds are paid separately), and you’re welcome to drop into the store for up to 1 year after your order is placed.
Socks and fit go together
A thin, knee-high ski sock with no seams across the ball of the foot is the right choice. Thick socks make the boot tighter without making it warmer — it’s the air inside the boot that insulates, and a boot that pinches gives you cold toes. Never wear two pairs.
Frequently asked questions
Ski boots are measured in mondopoint, which is the length of your foot in centimetres. Put your heel against a wall, measure to your longest toe and choose that size. The boot should feel snug when it’s new.
