Gear of the Week | Ski Boot Booster Straps

A small equipment upgrade with a big impact

by Sebastian Siep 12/23/2018
The Booster Strap was invented by Ray Fougere in 1999 and park and pipe skiers quickly realized that the strap stopped ski watch bruising. Nowadays, almost every ski boot manufacturer has its own strap technology, but nothing beats the original.

As a gross motor technician and power skier, it was always quite an ordeal for me for years to ski in mixed snow conditions or in ruts. As I tend to wear stiffer ski boots in order to be able to guide a more massive freeride ski precisely, I had to struggle with the bulky material, especially when I was tired. As soon as I no longer had a good position on the ski due to a lack of strength, I suddenly felt the hard edge of the ski boot. The blows from the ground were transferred very directly to the shin or calf.

Something similar happens, for example, when you're skiing in poor visibility. You somehow stand a little unsteadily on the spoon and expect the impact, which you try to process up to your upper back. Since I fitted the Boosters, this has been a thing of the past.

In summary, the Booster Strap is "just" an elastic strap that you lace around the shaft of the ski boot instead of the Velcro strap. It is used to make the flex behavior of the forward movement in the ski boot more direct.

This "only" is what makes the idea so ingenious. The booster ensures that the ski boot shaft is in direct contact with the lower leg at all times. My position on the ski is immediately better. There is no more digital flex. You can feel every little change in the ground without any sudden response from your body. In principle, the flex is more progressive, but not harder. You notice the onset of the base support and can guide the ski over it with the shin and control the necessary effort very well. It becomes sportier, but not more strenuous. The effort required is simply smoother and not as abrupt due to the full feel of the ski boot. So you can ski better and soon for longer...

This also refers to the construction of the booster. It is a fixed harness that is continuously tightened with a solid metal buckle and thus pre-tensioned. On the ascent, you can simply leave the strap very wide open with a short handle and thus avoid any annoying dangling of the buckle. The strap is interrupted by two to three elastic bands for the flexing area when guiding the skis on the descent. Two for the softer version, three for the Expert/Race or World Cup version. In the latter case, the elastic area is very short and probably too ambitious for most freeriders. You can think of it as an adaptive sports suspension and this controlled suspension travel simply gives you a lot of confidence. Of course, racing pros can get more out of it with their own, specifically trained suspension.

For me, the Expert version is very suitable. I recommend starting with this and if it is really still too stiff, cutting out a strip if necessary.

The simple construction of buckle+strap+rubber meant that the inventor's patent specification was very secure. It could not be reproduced by any major ski boot manufacturer on their own initiative. There are often similar constructions on racing boots from the factory, but these are always only partially elastic. In the rubber there is a continuous fixed area that does not flex. If you look closely, you will see that most racers also use an original booster to get the most out of the shoe. Some manufacturers use the original patent and mark this with a Powered by Booster logo. The patent is now due to expire soon and it is expected that almost all sporting goods manufacturers will make use of this invention. As long as the patent is valid, the piece of equipment is very expensive relative to its simple construction.

Fitting the straps is relatively simple and, if the strap is purchased from a professional retailer, it will also be fitted there - you just have to make sure that the metal buckle rests on the plastic and not on the inner boot.

I've been using the booster for around 3 years now and it pampers my calves and shins and simply makes my skiing days better. For me, it was one of the biggest equipment discoveries after having my ski boots fitted by a boot fitter.
