The Pulse ProFlex is a ski-boot accessory that stiffens up almost any two-piece ski boot by 15 to 30 per cent. It’s simple to install and won’t change your boots’ fit.
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.
Is It For Me?
- Do you have compromised stiffness for walk mode?
- Do you have compromised stiffness for lightweight boot?
- Do you have compromised stiffness for ease of entry?
- Are you a growing/improving junior racer?
- Are you a coach in hybrid boots for the grip and walk mode but want to drive a stiffer race-category ski?
- Are you a coach not sure if a boot is stiff enough for his developing racers?
- Are you an instructor with soft teaching boots still wants to perform?
- Are warm spring/summer temperatures softening your boots?
- Did you buy demanding new skis your boots can’t drive?
- Are you just looking for a stiffer boot?
The Pulse ProFlex addresses all these issues.
Most of you should be able to install the ProFlex by yourself. To help you with that, we've created a video that shows you how to install the ProFlex in your boot yourself.
Range of Motion Test
Many of you have been asking does the ProFlex affect the walk-mode in my boots? In the testing we’ve done and the feedback so far from testers, there’s no significant reduction in range of motion. We’ve also added a video showing the ROM with & without the ProFlex installed.
Concept to Prototype
Until now, it has been widely accepted that it isn’t possible to effectively stiffen a two-piece boot. Once we started working and experimenting with our prototype ProFlex and achieved the “impossible,” we quickly realized there was also a huge potential range of uses beyond simply stiffening hybrid boots (boots with walk modes). Instantly, the applications were obvious, but the problem of manufacturing proved difficult. We tried carbon fibre, vacuum moulding and even 3D printing, but none produced the result we were looking for. In collaboration with Pebax, we discovered injection moulding was the only way to get the performance we were looking for.
We now have a brilliant working prototype, but need your help to get to the ProFlex to production.
Who We Are
Experience is relative, expertise is not. Our team is made of bootfitters and skiers with over 50 years combined experience in the ski industry. We’ve bootfitted all over the world and have seen the wide range of needs and abilities from all corners, not just one resort or country. We are in direct contact with designers and engineers in the heart of the boot-making industry—Monte Belluna, Italy. More importantly, we are on the forefront of taking the voodoo out of bootfitting.
We’ve seen the trends and changes in the industry over the last 40 years. In the last 10 years, the classic boot design hasn’t changed dramatically, so manufacturers are looking to plastics and features to remain innovative and meet consumer demands
The ProFlex is one part of our repertoire, we’ve created our own fit system currently in the final tweaking stages before distribution. We’re flex testing boots and creating the Pulse Performance Rating (PPR), for each boot to better match the customer’s unique performance needs to the right boot.
Dissent Compression Socks:
We have added 2 kinds of Dissent compression socks into our rewards!! Check out which one works best for you:
Risks and challenges
Across almost all two-piece ski boot designs from every brand, the only variation we need to consider is the position of the instep buckle. For maximum compatibility, we’ve left the ProFlex without a pre-drilled hole, so that you are able to use it on almost any two-piece ski boot. We’ve also provided extra hardware to allow you to keep the instep buckle on your boot alongside the ProFlex. Lastly we are working on a compatibility chart for the ProFlex, chart will be avalible online soon.Learn about accountability on Kickstarter
