Ski touring boots: choosing well to ski well

Understanding how ski touring boots work

Ski touring boots are designed to easily alternate between uphill and downhill phases. They allow freedom of movement when climbing thanks to a cuff range of motion, freeing the shin for a smoother stride. Once at the summit, simply lock the boot to benefit from support similar to alpine ski boots. Visually, they resemble alpine models but are adapted to tech bindings or "Low Tech" bindings, used in ski touring. Brands like Dynastar, Head or Rossignol offer versatile and innovative boots in this area.

Weight: an essential criterion not to be overlooked

Boot weight can vary from 800g to nearly 1500g per boot. If you practice ski touring over long distances or with significant elevation gain, opt for a lightweight model. Conversely, for more downhill stability, you will need to accept a few hundred extra grams.

• Less than 1100g: ideal for uphill performance
• 1100g to 1300g: balance between ascent and descent
• More than 1400g: perfect for freerando or freeride

Dalbello and Lange notably offer stiff but effective models for skiers seeking downhill control.

Which closure system to choose?

The closure system directly influences foot support. Between classic buckles and BOA systems.

Different ski touring skier profiles

• Versatile: 2 to 4 buckles, to alternate ascent and descent
• Freerider: 4 buckles for optimal support in powder snow
• Advanced: BOA system or 2 buckles for a good compromise
• Expert: 1 buckle or BOA, for lightness and range of motion

K2 stands out with its lightweight one-buckle models designed for experienced tourers, while Head offers models with several buckles better suited for demanding descents.

Choosing the right size: the Mondopoint guide

As with alpine boots, touring boot sizes are given in Mondopoint (foot length in centimeters). This universal system allows better precision, although differences exist between manufacturers. Always try your boots with your technical socks to avoid pressure points or lack of support.

Categorization of ski touring boots

1 – Performance / lightness

Designed for competitors or skiers eager for uphill speed, these boots weigh between 800 and 1100g. They offer a large range of motion, sometimes up to 120°, at the expense of stiff downhill support.

2 – Versatile

The ideal compromise for many skiers: models between 1100g and 1300g offering a good balance between ascent and descent. Range of motion and rigidity remain adequate. These models fit a wide range of bindings and skis.

3 – Freerando

These boots are a bit heavier (1300g to 1450g) but provide optimal support and superior downhill comfort. They are ideal for skiers who climb to ski better on the way down.

4 – Freeride

Above 1450g, these models focus entirely on downhill performance. They have reinforced shells, up to 4 buckles, and large straps for maximum tightening. Range of motion is reduced but precision is maximized.

Technical criteria to consider before purchase

Closure system

Modern models feature up to 4 buckles, often combined with a wide tibial strap. The BOA system allows precise and even adjustment, especially useful for skiers seeking comfort on the ascent.

Rigidity and materials

• PU (plastic): economical, rigid but heavier
• Hybrid (carbon + plastic): good compromise

Rossignol and Lange offer several reinforced plastic models suited for versatile or freerando skiers.

Flex: a rating to nuance

The flex rating gives an idea of rigidity but remains specific to each manufacturer. It should therefore not be compared between brands, but only within the same range. For example, a Dalbello boot with a flex of 120 will not behave like a Head boot with the same value.
