BOOSTER MEDIUM

Booster Strap Medium – The Classic for More Precision in Ski Boots

The Booster Strap Medium is for many racers, coaches, and performance-focused skiers the perfect balance between comfort and uncompromising performance. Those who want to ski their boots more directly, precisely, and with more control, without sacrificing harmonious flex, will find one of the most effective tuning tools in the entire alpine ski sector here.

Compared to a conventional power strap, the Booster Medium works elastically. This creates significantly closer contact between the shin and the ski boot. Power transmission is more direct, the flex becomes more progressive, and the ski reacts more precisely to every impulse. This is exactly why the Booster Strap ski boot has become standard equipment for many racers in national and international racing.

Booster Strap for Performance Skiing and Ski Racing

Technical Data

Why the Booster Medium is Immediately Noticeable on the Slopes

In practice, one of the biggest differences between average and perfect ski boot setups is the connection between the leg and the boot.

This is exactly where the Booster Medium comes in.

It improves:

• direct power transmission
• faster ski reaction
• more precise edge grip
• harmonious pressure build-up
• smoother behavior at speed
• more control on hard snow

Especially on icy race tracks or with an performance skiing style, you immediately feel how much more precisely the boot works.

Progressive Flex Instead of Hard Stop

Many stock straps create an abrupt resistance as soon as pressure is applied to the boot tongue.

The Booster Medium works differently.

The elastic construction creates:

• a consistent flex progression
• controlled pressure build-up
• better balance
• more feel for the ski
• smoother ride

From a racer's perspective, this makes the boot feel significantly more lively and at the same time more controlled.

More Precision in Race Training

Especially in ski racing, small material details often make the decisive difference.

The Booster Medium ensures:

✔ more direct impulse transmission

✔ less play in the cuff

✔ better feedback from the ski

✔ higher precision when changing turns

✔ more confidence at high speeds

That's why it is the preferred choice for daily race training for many athletes and coaches.

The Ideal Middle Ground Between Soft and World Cup

The Medium is the all-rounder in the Booster series.

It offers:

• more support than the soft version
• more comfort than the toughest World Cup models
• high precision without excessive stiffness
• perfect balance between control and mobility

For many ambitious skiers, this specific tuning is the most sensible choice.

Our Advice from Racing

In our experience, the Booster Medium is the most versatile strap in the entire Booster program.

We recommend it for:

Anyone who trains regularly and skis in an athletic ski boot almost always benefits from this upgrade.

When High-Quality Power Straps Really Make Sense

Many skiers invest in new skis and forget about the ski boot.

However, the connection between the shin and the boot directly influences:

• skiing feel
• precision
• balance
• reaction speed
• control

A high-quality Booster Strap can significantly improve these properties without having to buy a completely new ski boot.

Differences to Inexpensive Standard Straps

Normal Velcro straps:

• fix the cuff
• hardly work with the leg
• often create free play

The Booster Medium:

• works progressively
• improves contact with the boot
• increases precision
• optimizes power transmission
• provides a significantly sportier skiing feel

Use & Care Instructions

The Booster Medium replaces the standard strap on the ski boot.

For optimal results, we recommend:

• professional installation
• correct positioning above the boot tongue
• individual adjustment of tension
• regular checking of the fastening

The correct setting significantly determines the effect of the strap.
