“THE PULSE PROFLEX IS A SKI-BOOT ACCESSORY THAT STIFFENS UP ALMOST ANY TWO-PIECE SKI BOOT BY 15-30%. IT’S SIMPLE TO INSTALL AND WON’T CHANGE YOUR BOOTS’ FIT.”
Interesting little aftermarket ski boot product by Pulse Labs out of Revelstoke, Canada. Not exactly sure how you get your hands on a pair if you didn’t get in early on the Kickstarter campaign but if you’re a retailer you can contact them about carrying them in your store HERE. Here’s the pitch:
“In 2019, skiers are compromising performance for features and convenience. The ProFlex was initially conceived because boots with walk modes, tech fittings, thinner walls and lightweight plastics are simply not providing the stiffness their true alpine counterparts deliver. The Pulse ProFlex allows skiers to choose features and convenience without compromising performance.
The stiffer skis we need for mixed snow conditions at resorts demand stiffer, more powerful boots. We want skiers to be able to ski any ski they want, in any terrain they want, at any temperature. This is where the ProFlex comes in. The ProFlex increases the stiffness of the boot by adding material at the main flex point—the fold between the shin and foot.
Current accessories marketed to stiffen boots can actually do the opposite. Elasticized power straps give a better hold around the upper shin, and cuff plates increase the height of the boot, but these both just increase the leverage a skier has over their boots, making them softer.”
STIFFNESS OF A SKI BOOT: AKA FLEX RATING
“There are no standards for ski boot flexibility. Ski brands have long tried to create a set of industry standards, to no avail. Flex ratings usually range from 70 to 130 (beginner to advanced) and vary by manufacturer; meaning one brand’s 130 can be another brand’s 110. Even within a brand’s own product range, a 130 in one model can differ dramatically from a 130 in another. From our own testing, we’ve found equal flex ratings can vary by as much as 40 per cent.”
