BOOSTER WORLD CUP

Booster Strap World Cup – Maximum Control for Uncompromising Ski Racing

The Booster Strap World Cup is the toughest and most direct version of the legendary Booster Strap series. Developed for racers, FIS athletes, and skiers with the highest demands for precision, this Booster Strap ensures an almost play-free connection between the shin and the ski boot. Those who are looking for every hundredth of a second in ski racing know: not only the ski and ski boot determine performance – the connection in between often makes the decisive difference.

Compared to conventional power straps, the Booster World Cup eliminates almost all free play in the cuff area. Pressure builds up immediately, power transmission becomes more direct, and the ski reacts more precisely to every movement. This is precisely why this model has been part of the equipment of many World Cup, Europa Cup, and FIS racers for years.

Booster Strap World Cup – The Race Upgrade for Uncompromising Ski Boots

Technical Specifications

Why the Booster World Cup Sets Standards in Racing

Anyone who has ever skied with a correctly mounted World Cup Booster will notice the difference after just a few turns.

The boot reacts:

• more directly
• more precisely
• more aggressively
• more controlled
• more calmly under high loads

Especially on icy slopes or during race training, the improved connection between the leg and the ski boot ensures more control and safety.

Maximum Power Transmission Without Energy Loss

In racing, every movement counts.

The Booster World Cup minimizes energy losses through:

• less play in the cuff
• more direct shin contact
• faster pressure build-up
• immediate ski reaction
• more precise edge grip

This difference is particularly noticeable with aggressive lines and high loads.

More Precision at High Speeds

It's no coincidence that Booster Straps are used in the World Cup.

The World Cup Strap ensures:

✔ maximum control at speed

✔ direct feedback from the ski

✔ higher stability at the turn entry

✔ more precise edge pressure

✔ consistent performance on hard slopes

Especially in giant slalom and Super-G, racers benefit from this direct connection.

Significantly More Performance Than Standard Straps

Normal power straps hold the cuff together.

The Booster World Cup does significantly more.

Advantages over conventional straps:

• progressive pressure build-up
• higher cuff stability
• more direct power transmission
• less cuff play
• more precise reactions
• better control on ice

For racers at race level, there is hardly a more sensible ski boot tuning.

Our Assessment from Racing

The Booster World Cup is not a comfort product.

It is aimed at skiers who:

• actively build pressure
• ski with clean technique
• reach high speeds
• seek maximum precision
• are involved in racing

For pure recreational skiers, this tuning is often unnecessarily stiff.

For ambitious racers, however, the World Cup Booster is one of the most effective upgrades for the entire ski boot.

For Which Skiers Is the World Cup Suitable?

We recommend it for:

• FIS racers
• Masters racers
• DSV squad members
• Europa Cup athletes
• World Cup-oriented skiers
• very performance-focused skiers with race boots

Anyone who rides a soft recreational boot will not be able to fully utilize the benefits.

Why High-Quality Booster Straps Are Standard in Racing

A high-quality Booster Strap ski boot improves:

• power transmission
• precision
• balance
• control
• cuff stability
• reaction speed

That's why Booster Straps have been a permanent part of many racers' equipment for years.

Installation Note

The Booster World Cup replaces the standard power strap of the ski boot.

For maximum effect, we recommend:

• Installation by a specialist dealer or bootfitter
• correct positioning over the boot tongue
• individual adjustment of the tension
• regular checking of the fastening

The correct setting is crucial for performance.
