Booster 3 Elastic w/Stiffener
The Booster Strap World Cup offers maximum boot performance and ski control, increases comfort, and aids the prevention of shin bang. It does this by eliminating any empty space between the shin and the ski boot’s tongue. Booster Strap elastically fastens the leg and the ski boot together and provides direct ski control so the skis will initiate sooner and transition out of the turn faster. The stiffness varies between the different models.
