Model selection The choice must be made taking into consideration the following parameters: 1. Weight/Size For the large/heavy athlete, the Booster Medium or the World Cup is more suitable, for the the Booster Soft for light/small athletes. 2. Aggressiveness For the aggressive skier, the Medium and World Cup models are the most suitable, for the skiers, the Booster Soft 3. Discipline For technical disciplines, Medium or World Cup are preferable, for fast skiers the Soft 4. Ski boot plastic hardness Hard boot ® Booster Medium or World Cup, soft boot ® Booster Soft 5. Ski stiffness Hard ski ® Booster Medium or World Cup, soft ski ® Booster Soft We recommend starting with a softer model rather than a harder one. A softer model will have a lower elastic response, but will make it easier to feel the Booster's characteristic benefits. If the skier starts with a model that is too the benefits of the velcro strap.
Booster Straps offer maximum ski boot performance, extraordinary ski control and shock absorption protecting the shin. The BOOSTER STRAP must be routed outside the rear spoiler and inside the plastic shell, against the tongue at the front. The elastic is then stretched by about a centimetre. If, from the very first turn, you don't notice a dramatic difference in the ski's response, the BOOSTER STRAP is too loose or incorrectly installed. On the other hand, if after a few turns you feel that something is pushing you backwards, the BOOSTER is too tight. Bear in mind that, as in any sport, your skill level improves with experience, and your BOOSTER setting may vary over time. Adjust it to your skill level. Note: on boots with a high front shell, the elastic part will be behind the front shell. It is recommended to remove the Velcro ™ band which is no longer necessary or desirable.
