I had always skied with booster strap in my free skiing boots and I love the feel. I believe I understand the theory / idea behind it, which is provide progressive flex.
I switched to Head Raptor B2 race boots about a month ago and never really bothered to try booster straps on them. But now that the ski season is over and I am in heavy withdrawal mode, I am thinking about putting booster straps on them for future seasons.
The boot itself comes with a booster strap already. On head's website it stated that the strap was licensed from skimetrix which holds the patents to elastic booster straps. The flex certainly felt progressive and similar to my previous free skiing boots with booster strap. So my first question is... will I benefit from a booster strap in addition to the one already on the boot?
Assuming that another booster strap is helpful, my next question is where to put it.
Option 1: Wrap around the top of the liner to tighten it around my calf. Since it's not attached to the shell, I guess it's not really doing anything other than making the liner more snug against my foot... or will this actually do something?
Option 2: attach booster strap to the back of the shell, and route the front elastic part above the existing strap like in the first picture in option 1. I think this would essentially create two booster straps. What will this do? Just thinking this through... I should be able to flex the boot from a higher point due to the double strap... more leverage and power?
Option 3: attach booster strap to back of shell like option 2, route front elastic portion under the boot shell and tighten, then put stock strap over the booster strap and tighten. I am not exactly sure what this will do... elastic flex over elastic flex?
Thoughts / advice? Thanks in advance!
