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.
