HOW DO I CHOOSE THE RIGHT SIZE FOR MY LANGE SKI BOOTS?

Choosing your ski boots isn't always easy. But it's an essential step if you want to enjoy unforgettable moments on snow. So it's important to find the right pair for your size and shape.

A boot that doesn't fit properly, is too big or too small, will be a source of discomfort. To make sure you get the best fit, two measurements need to be taken into account: the length and width of your feet.

KNOW YOUR FOOT SIZE IN MONDOPOINT

Measurement n°1 : Lenght

The sizing system commonly used in ski boots is MONDOPOINT sizing. This measurement refers to foot length from toe to heel expressed in centimeters. For example, a 26.5 MP boot is suitable for a foot measuring 26.5 cm in length.

For correct boot sizing, do not forget:

1) When flexing into the boot, your toes should have minimal space against the end of the boot. Proper fit is toes just lightly touching the front and pull back when you flex forward.

2) To help avoid pressure points, boot buckles should never be overly tightened. Instead look for a more precise initial fit that doesn’t rely on you overly-tightening the buckles. If you need to tighten the buckles completely to get the retention you desire, the boot is too big and you should downsize.

3) The liner will pack out and conform to your foot over time so look for a snug, yet comfortable fit.

4) Ski socks will make a big impact regarding the fit and comfort of your boot. Thicker socks can often limit blood circulation and provide less warmth, while a thinner sock will offer greater sensitivity and precision.

FINDING THE RIGHT FIT FOR ME

Measurement n°2 : Width

To choose the appropriated model, you need to make sure that the fit of the shoe is adapted to the shape of your foot. The Fit of the boot (or last) is the width of the foot measured at the 5th metatarsal (widest part of the forefoot). It determines the level of control and precision of the skier.

Lange is offering three different fits to adapt precisely to different foot shapes and widths: narrow, medium and wide.

1) PRECISION FIT (92-95mm): Recommended for competitors and ideal for narrow feet.

2) PERFORMANCE FIT (97-99mm): Suitable for medium-width feet.

3) COMFORT FIT (100-102mm): Ideal for wide feet.

For a good ratio between comfort and control, choose a boot that matches the overall volume and length of your foot. If you are looking for precision, choose a narrower last. However, do not choose a boot that is too wide because you may have less control of your skis.

LANGE RS 120 SC

High-performance racing ski boots with a narrow 97 mm last, designed for junior racers and women who demand maximum precision, direct power transfer and World Cup-inspired performance.

The LANGE RS 120 SC is built using technology developed by Lange's racing department and is engineered for sporty and competitive skiers with narrower feet. The SC (Short Cuff) construction features a lower cuff height, making it an excellent choice for skiers with shorter lower legs or a smaller build. This design promotes a more natural stance, improved ski contact and greater freedom of movement without compromising control.

The innovative Dual Core shell construction, anatomically shaped shell and heat-moldable Dual 3D Full liner combine outstanding precision, exceptional comfort and immediate response to every movement. With a flex rating of 120, the RS 120 SC delivers the support required for aggressive skiing and competitive racing.

Who are these ski boots for?

The LANGE RS 120 SC is designed for experienced junior racers, competitive skiers and advanced athletes with narrow feet who require maximum precision and a direct connection between boot and ski. Thanks to the lower cuff height, it is also an ideal option for women or smaller skiers who often find traditional race boots too tall.

Ideal for:

junior racers
women with an athletic skiing style
competitive skiers
high-performance carving
gate training
hard-packed and groomed slopes
advanced and expert skiers
skiers with narrow feet

These boots perform best during dynamic, high-speed skiing where precision, responsiveness and complete control are essential.

How do the boots perform on snow?

The RS 120 SC delivers exceptionally precise ski control, immediate response and outstanding stability, even during aggressive skiing. Thanks to its race-inspired shell geometry and Dual Core construction, power is transferred directly to the ski edges with minimal energy loss.

The lower cuff allows for a more natural body position and more effective ankle and knee movement. This results in improved balance, better edge control and more precise turn initiation.

Key performance characteristics:

immediate power transfer
maximum steering precision
excellent edge control
outstanding stability
highly responsive feel
progressive flex
race-inspired performance
exceptional control at high speeds

DUAL 3D LINER

A liner preformed twice in 3D. The inside of the liner is preformed to support the foot while the outside is preformed to the shape of the boot to limit movement and thus ensure superior precision and power transfer. Available in different levels of customisation, the DUAL 3D LINER WORLD CUP, FULL, PRO, PERFORMANCE and SPORT liners provide an accurate fit for optimal comfort and control.
DUAL CORE

Utilizing our revolutionary new process, both soft and rigid versions of the most responsive high-performance plastics are simultaneously injected and targeted to key areas of the boot. The result of this innovative new process creates our proprietary sandwich shell construction – DUAL CORE By sandwiching a softer plastic core within more rigid plastic, we are able to drastically enhance elastic tension. So as you drive and flex into your boots, DUAL CORE actively compresses and expands – harnessing potential energy to deliver explosive power, snap, and rebound. Imagine World Cup precision and response, easy entry-and-exit, and a new level of ski boot performance as reactive and dynamic as your own body. - Hard plastic is targeted to the areas that transmit power and energy to the ski. - Softer plastic is targeted to the areas that wrap the foot and lower leg.
NATURAL STANCE

Lange's unique NATURAL STANCE compliments modern ski designs, offering a lower ramp angle 4° and more neutral, upright stance to increase balance and control fo more efficient power transfer and less quad fatigue.
SHORT CUFF

About 15 mm shorter upper part at the back of the cuff and 20 mm at the front allows skiers with shorter poles natural posture and range of motion for greater comfort.
