Booster Strap for Ski Boot by SkiMetrix World Cup

As an expert-level skier logging 100+ days on snow each season, the Booster Strap for Ski Boot by SkiMetrix World Cup has legitimately changed my boot game. The construction feels rock solid — no flimsy nylon — and it cinches down smoothly so I can fine-tune the tension exactly how I want it. On long charging days, I can tighten up for locked-in edge control, and on softer snow I back it off without fuss. It noticeably reduces heel lift and gives a more direct feel through every turn. I ski a mix of big mountain, ice, and crud, and this strap has held up under all of it with zero loosening or wear. Simple install, no weird quirks, and it actually makes my boots perform closer to how I want them to. If you’re pushing hard every day and want that extra connection to the snow, this is worth every penny.

We placed these on the single buckle rear entry ski boots for redundancy and safety. They also work to increase the stiffness of the same boots without the normal loss of comfort that comes from increasing the stiffness in the shell. Instead of riveting the strap, we used velcro on the back of the boot and the inside of the strap and we never have to take it off or adjust it, even without having to rivet into the boot.

Hi everyone, This is a great product to incorporate into your boot system. Just know, there are levels of strap tension. For example “World Cup” is synonymous with a very rigid strap for limited flex. This is what I purchased not knowing there were different levels, I just knew the name “booster” but not the level, example “World Cup”, “Expert” and “Intermediate”. Now I know - duh. All I know is that I purchased the “World Cup” but a great technician (Sam) at Surefoot in Park City, showed me how to relieve the tension of the strap by cutting an internal band. ATTENTION: don’t do this unless you know exactly what to do! Otherwise, you’ll ruin the strap. The theory of the strap is like a thick rubber band that creates more tension as it is expanded and less when relaxed but there is some amount of tension. Unlike the typical strap that comes on most boots that when you crunch or push your shins into the tongue of the boot, you engage pressure through the boot in to the skis. But the typical strap is on/off and once you disengage the shin from the boot tongue, there is no pressure. The booster strap changes that paradigm by increasing/decreasing the amount of pressure to the boot tongue in increments, not on/off. I hope this helps

Poor craftsmanship. Made in USA with no attention to quality. Quite disappointing considering it’s essentially a $60 ratchet strap. Sending these back.

Not the easiest to install, but the improvement in boot fit makes it well worth it.

Booster straps are great. Much better than the Velcro straps that come with my original lange boots. These don’t slip and ice doesn’t get in them.

I have skinny calves and these really help lock down the boots around my ankles and lower calves. Quick and easy to adjust - crank down when riding, then release for the lift ride back up

I have used this power strap two full days with my fairly new racing boots. When using the strap, I feel that I have so much more control over my skis, on and off-piste. The item that I received was an open box item but it was in new-like condition. No problem there. I can't recommend it highly enough.

Great product! As an expert skier, I noticed that turn initiation was quicker. Overall ski experience was very responsive. Any shin shock was eliminated. Easy to install.
