FIT: 100

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. For a good ratio between comfort and control, choose a boot that matches the overall volume and length of your foot. Fit between 92-95 mm: Narrow, Fit between 97-99 mm: Medium, Fit between 100-102 mm: Comfort

FLEX: 100

The “flex” of a boot indicates the level of support that boot will deliver. The greater (stiffer) the flex index, the more rigid and reactive the boot will be. The lesser (softer) the flex index, the more tolerant and comfortable.

LEVEL: 100

Choose the boots which offers the best ratio between comfort and performance. For a beginner skier, we recommend a flexible flex (<80) and for an expert skier we recommend a higher flex (>90).
