TECHNOLOGY:

 

3M™ Thinsulate™: These products retain as much heat as possible on a smaller surface area. The technology is warm, lightweight and offers excellent freedom of movement in both clothes and boots, even in cold weather.

Thinsulate is a material made up of fine synthetic fibres that store a lot of air and help ensure warmth.

The 3M company is renowned for its numerous innovations, already found in Neil Armstrong's gear.

The special Thinsulate Insulation fibres ensure a high level of comfort as well as efficient breathability and anti-moisture action, even when practising sports that generate a lot of sweat.

Sensor Grid: Two internal widths based on the same structure to offer a close and anatomic fit. This technology reduces the shell by 10% (refining and enhancing its rigidity) and improving accuracy with a diagonal frame position.

 

FOOT WIDTH:

 

102 mm LAST: 102 mm foot width aimed at skiers with a large foot size or skiers looking for added comfort over a long period of time.

 

FLEX INDEX:

 

 

 

 

 

FLEX INDEX: The flex is the boot's flexibility index. The greater the flex, the more rigid and reactive the boot. On the contrary, a soft flex will be more tolerant and comfortable. The flex of your boot is chosen in relation to your skiing level as well as size.

Men's Flex Index:

  • Flex from 60 to 70: beginner to intermediate
  • Flex from 80 to 110: intermediate to advanced
  • Flex above 120: expert

Women's Flex Index:

  • Flex from 50 to 70: Beginner to intermediate
  • Flex from 80 to 70: Intermediate to advanced
  • Flex from 100 to 110: Expert

Important: A flex that is too rigid for the average skier will impede progression. For a heavy and powerful skier, it is essential to increase the flex.
