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.
