What does flex mean on ski boots?

Flex describes how stiff the boot is when you bend forward. Lower numbers are softer and more forgiving, higher numbers stiffer and more precise at speed; around 100 is an all-round level for experienced skiers. The number isn’t standardised between manufacturers, so compare within the same brand.

What is the last and which one suits me?

The last is the boot’s width across the ball of the foot — narrow about 98 mm, medium about 100 mm, wide about 102 mm. A medium last suits most people. The shell can be heat-moulded for more room.

What’s included in a boot fitting?

We analyse your foot, fit the boot, heat-mould the liner and grind or punch the shell where it pinches. Buy your ski boots from us and boot fitting is free for 1 year from purchase — you only pay for materials, such as a custom-moulded footbed. You’re welcome to drop into our store at Isaberg, Sweden for up to 1 year after your order is placed.

Do I need a custom footbed?

The standard footbed works for most people with a normal foot. A custom footbed is moulded to your footprint and gives better heel hold and less fatigue — it’s the single biggest fit improvement you can make without changing boots.

About Salomon S/Max 120 GW – Ski boots

The Salomon S/Max 120 GW features a revolutionary design and was developed together with Salomon's Fast Collective, paving the way for a radically new way of making ski boots. The boot combines low weight with a perfect fit, so you can confidently and easily carve your own path. This is so you can enjoy great skiing to the fullest.

GripWalk soles come pre-mounted, meaning you can enjoy secure grip and excellent comfort when walking. The Coreframe construction features a thinner shell that makes the boot lighter, more agile and more responsive. At the same time, the new Custom Shell HD technology allows the pre-shaped, seamless liner to be adapted to the foot in less than ten minutes.

The reinforced Coreframe construction with carbon fiber and Sensitive Shell improves power transfer. Coreframe provides lightness, increased feel and increased strength. It is an insert that guarantees the boot's stiffness after the Custom Shell HD process.

The goal of the Custom Shell HD method is to be able to adapt the shape of the lower shell of the boots in just ten minutes. The thinner side construction and the new shell materials mean that the foot is closer to the shell, which provides better feel, more power and direct power transfer. A featherlight construction provides a natural snow feel and the Sense Amplifier and the two-position strap provide the best flex and adjustability for optimal performance.

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.
