Does not stiffen the boot, but changes the perception or range of flex to provide forward pressure instantly as your start your turn.
The elastic of the Booster acts as a spring or cushion preventing the shim from banging against the front of the boot.
Not just for racers. The Booster helps secure your leg to the boot in a positive fashion which is needed by all skiers and for that matter all movement. Casual sport enthusiasts need proper fitting snug footwear to enjoy their sport.
If between strap models, go with the stiffer one. As you use the Booster Strap typically you get more proficient and therefore would want the stiffer one. If you are aggressive definitely go stiffer.
You adjust the stiffness of the Booster by stretching the elastic webbing to the desired tension for your strength and ability.
A good rule of thumb is to match the flex index of the boot with the model Booster Strap. Also remember there is a grey area between models. Less than 100 flex – Intermediate, 110 to 130 –Expert, and greater than 130 the World Cup.
