CHOOSING THE RIGHT FIT
Your choice of ski, boot design and size will always be a very personal and subjective decision. Here we have compiled some factors that should be taken into account when deciding on which ski size to choose.
Optimal ski length is determined according to (in order): weight, physical ability, skier height and type of skier (aggressive/non-aggressive). Less aggressive skiers should choose a smaller size, while more aggressive and experienced skiers may want to choose a size up.
- Measure your height: 175 cm
- Define your skiing level: experienced
- Choose your ski type: piste
- Calculate your required ski length: 175 + Experienced (piste) = 175 + [-5.0] = [170, 175] cm
