More about footprint analysis Directly to your analysis data

There's one moment where pace is decided: when your big toe leaves the ground. It's the final link in the propulsive kinetic chain – and the most powerful lever for propulsion your body has. In most shoes, it goes unused.


The Big Toe Trainer activates exactly the muscles that generate that push-off. Two exercises– Load and Launch – build strength, stability and elasticity right where seconds are won insport. One device, two exercises, three minutes a day.


Developed by Dr. Jan-Peter Goldmann at the German Sport University Cologne, together with biomechanist Lee Saxby. Precision-made in Germany from glass-fiber reinforced high-performance polymer – light, stiff, maintenance-free. Built to transfer every repetition cleanly, year after year.


Proven in lab studies: up to 70% more strength and 6% more muscle volume in seven weeks – even among pros. More push-off, more stability, lower injury risk.

Part of the Big Toe Power System
THE MISSING LINK

The Big Toe Power System is the decisive link to full foot function and creates a complete cycle where other approaches stop. 

It starts with reactivation through our socks and the alignment of the big toe using the spacers. The central power module is the Big Toe Trainer, which specifically builds the musculature that is crucial for propulsion. Our shoes give your regained strength the necessary space to permanently restore natural function in everyday life and while running.
