About K2 Recon X BOA 120 – Alpine ski boots

The K2 Recon X 120 BOA is a modern alpine boot for skiers who want to combine high performance with a contemporary fit. As part of the brand new Recon series for the 26/27 season, it offers the same well-thought-out construction as other models in the series, but with a flex of 120, providing a perfect balance of power, precision, and responsiveness.

The new BOA® Fit System makes the fit easy and precise. Instead of traditional buckles over the foot, the BOA system evenly encloses the foot, resulting in better contact between the foot and the shell. Therefore, you get a more direct feel for the ski and better control in every turn.

With a last of 98 to 100 mm, the K2 Recon X 120 BOA offers a fit with a good balance of precision and comfort. At the same time, FastFit Instep makes it easier to put on and take off the boot, which is appreciated on cold mornings. If you want to know more about how to choose the right last and flex, we recommend our buying guide.

The fully heat-moldable shell allows for a more personalized fit. Additionally, the P4 liner provides an anatomical and comfortable feel right out of the box.

The shell is made of TPU to provide a smooth and progressive flex, while the cuff in PP contributes with low weight and quick response. The fixed spine construction along with a 4-degree ramp angle also provides a balanced position and efficient power transfer throughout the turn.

In short, the K2 Recon X 120 BOA is an excellent choice for advanced skiers who want modern BOA technology, high comfort, and a powerful flex that works equally well for fast carving turns and varied riding all over the mountain. If you're looking for more models, you can find our entire range of alpine men's boots here.

FAQ

Who is the K2 Recon X 120 BOA suitable for?

The K2 Recon X 120 BOA is suitable for intermediate to advanced skiers who are looking for a sporty boot with high precision and a powerful, yet still forgiving, flex.

What is the advantage of the BOA® Fit System?

The BOA system evenly encloses the foot and makes it easy to fine-tune the fit. Therefore, you get better comfort and a more direct feel for the ski.

Is the K2 Recon X 120 BOA heat-moldable?

Yes. The shell is fully heat-moldable and can be adapted to the shape of your foot. Together with our bootfitting (/pages/bootfitting), you can create a very personalized fit.

How wide is the K2 Recon X 120 BOA?

The boot has an MV last of 98 to 100 mm. This makes it suitable for many skiers who want a sporty fit with high precision and good comfort.

What is the difference between Recon X 110, 120, and 130?

The biggest difference lies in the flex. The Recon X 120 offers more support and power transfer than the 110 model, while being slightly more forgiving than the Recon X 130.

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.
