Product Information "Booster Strap Green Medium Expert"

The Booster Strap Green Medium consists of a high-strength elastic strap and a finely adjustable metal buckle. The Booster Strap elastically connects the leg to the boot and transfers the skier’s movements directly to the ski. Designed and manufactured to meet the needs of World Cup athletes. The Booster World Cup Medium is ideal for athletes of medium height. The fantastic BOOSTER STRAP Medium is worn by numerous superstars, including Olympic champions such as Ted Ligety and Bode Miller.

Installation of the Booster Strap Green:

The BOOSTER STRAP should be routed outside the rear spoiler and inside the plastic shell against the front tongue. The elastic strap is then stretched by a few cm. If you don’t notice a dramatic difference in how the ski responds during your first turn, the BOOSTER STRAP is too loose or installed incorrectly. However, if after a few turns you feel like something is pushing you backward, the BOOSTER is too tight. Keep in mind that your skill improves with every experience, so your BOOSTER setting may vary over time. Adjust according to your ability.

  • Note: On boots with a high front shell, the elastic section is located behind the front shell.
  • It is recommended to remove the Velcro strap, as it is no longer necessary or desirable.

Rated 5 out of 5 stars

More direct power transmission, progressive flex, no "shin bang"

More control and comfort with a sportier ride. Increased rebound: The strap stores energy during flex and releases it again at the end of the turn, which supports edging.
