The Big Toe PowerPro: Unlock your propulsive power! 


Your feet carry up to 8x your body weight during sports — yet most of us never train them.
The Big Toe PowerPro is an affordable, easy-to-use training device that boosts foot strength where it matters most — enhancing balance, stability, and performance, especially for high performance athletes. It targets the big toe flexors, crucial for power and pressure control in every step in sports.
The stronger the big toe, the more propulsive power it can generate, enabling you to run faster, jump higher and change direction quicker.

1 machine - 2 exercises - 3 minutes

Unlike any conventional and complicasted exercises, the Big Toe PowerPro propels your athletic power to previously unreached levels in the convenience of your home. We developed this professional training device for athletes who want to unleash their full propulsive power. It is an innovative, simple training tool that can provide an unfair advantage for you in any sport.

Why the Big Toe PowerPro?

  • Scientifically proven
  • Boost toe strength by up to 70%
  • Increase muscle volume by 6%
  • Improve foot stability and performance
  • Customizable resistance for all levels
  • Compact, affordable, and easy to use

Designed by scientists – used by professional athletes – now available to you!

Dr. Jan-Peter Goldmann, a foot biomechanics expert from the German Sport University Cologne, has spent 20 years studying feet — using 3D scans and lab tests to show that targeted foot muscle training can significantly boost strength, volume, and athletic performance, with gains of up to 70%, even among pros. The German Sport University is highly respected worldwide for its contribution to the science behind sports, health, and performance enhancement.
Scientific studies conducted at the German Sport University Cologne have demonstrated the remarkable effectiveness of the Big Toe PowerPro training device. Research led by Dr. Jan-Peter Goldmann showed that targeted training with the Big Toe PowerPro resulted in significant improvements in foot strength and function — including up to 70% increases in muscular strength and 6% gains in muscle volume within just seven weeks. These findings confirm that even the often-overlooked foot muscles, when properly activated and trained, can deliver measurable performance benefits.

Here is what the pros say:

The Big Toe PowerPro is for athletes, coaches and trainers that want to improve:

  • Push-off power
  • Change of direction and agility
  • Ground contact and force transfer
  • Running efficiency
  • Jumping mechanics
  • Foot arch support

Superior to all existing training tools

Functional anatomy and powerful propulsion

WRONG: When athletes can't properly engage the big toe and its supporting muscles and tendons, they instinctively avoid loading it — leading to a loss of up to 35% in propulsive power and triggering compensatory movement patterns.
CORRECT: The key to powerful, high-performance running lies in leveraging the big toe as a slingshot lever — harnessing the elastic recoil of its muscles and tendons to deliver the final explosive push off the ground.

Two simple exercises

Just two simple exercises with the Big Toe PowerPro — taking only three minutes, four times a week — can make a powerful impact. In as little as 8 weeks, this focused routine strengthens the often-neglected foot muscles, especially the big toe, which plays a key role in speed, stability, and explosive power. The result: better performance in any sport.

Most of us never consciously train our foot muscles — yet they’re key when the forces of up to 8x body-weight act on the foot in sports. That’s why we, together with Dr. Goldmann, created the Big Toe PowerPro: a breakthrough device that strengthens your big toe through natural flex and toe extension. With its stable footplate and adjustable resistance bands, it delivers fully customizable, effective training for the foundation of your movement.

Great for efficient and lasting rehab results!

Say goodbye to complicated and ineffective rehab—train just three minutes a day with the Big Toe PowerPro to boost foot strength and increase big toe propulsive power by up to 70%.

Made in Germany

Align Your Big Toe & Unleash Your Superpower

To complement your training with the Big Toe PowerPro, we’re excited to introduce the Big Toe Socks and Big Toe Spacer — the perfect supplementary tools to take your foot training to the next level. These two products work in harmony to help isolate, align, and activate your big toe throughout every session. The Big Toe Spacer gently guides your toe back into its natural, straight alignment, while the Big Toe Socks keep it supported and comfortably in place. This setup ensures optimal form during your exercises, helping re-establish natural foot structure and function. A straight, strong, and stable big toe is the secret to unlocking foundational strength — driving more explosive power, faster sprints, higher jumps, and sharper, more controlled cuts across any sport.

A chain is only as strong as its weakest link:

In sports, that final link is often the most overlooked: the big toe. During the propulsive phase of movement, whether sprinting, jumping, or changing direction, the big toe is the last point of contact with the ground, responsible for transferring force and generating forward momentum. If it’s weak or misaligned, it compromises the entire kinetic chain. But when trained and functioning properly, it becomes a powerful driver of athletic performance, turning every step into a stronger, faster, and more efficient movement.

The Big Toe Company

The Big Toe PowerPro is the result of visionary leadership by Sebastian Bär, founder and CEO of Joe Nimble - The Big Toe Company - who brought together a world-class team of scientists, inventors, coaches, industrial designers, wood specialists, and elite engineers. United by a shared mission, they created a scientifically proven, easy-to-use training tool that enhances performance by targeting the big toe — the powerhouse of athletic movement. Handcrafted in Germany to the highest standards, the Big Toe PowerPro combines precision engineering with functional design to deliver unmatched quality and results.
