02 / THE COLOR OF MOVEMENT
When movement becomes color.
Thermochromic materials in the sole respond to foot temperature. See the changing colors and turn today’s movement into tomorrow’s motivation.
Stages illustrate the design concept. Actual color response depends on foot temperature, activity time and conditions. The shoes do not directly count steps.

THE SCIENCE BEHIND THE QUESTION / CATALOGUE03
From foot heat. To a new idea.
BALREX places thermochromic materials in the sole to respond to foot temperature during walking and running. University of Utah research offers background on how foot temperature changes during walking.

The study proposes that both mechanical and physiological factors may contribute to foot temperature responses.

GOOD TO KNOW
Before your first step.
Does the color tell me my exact step count?+
No. BALREX uses thermochromic materials that respond to foot temperature. The approximately3,000,6,000 and9,000-step stages illustrate the design concept; actual response varies by person and conditions.
How do the walking and running shoes differ?+
The walking model features color changes in the core window and Archon support. The running model features medal graphics revealed through the transparent outsole. Archon is for the walking model.
Can I buy a pair now?+
BALREX is preparing for launch. Contact us for product updates, supply opportunities and product experience inquiries.
Are exercise or joint-protection benefits proven?+
Muscle activation and landing characteristics are being tested. We do not claim numerical benefits or medical efficacy before confirmed results are available.
Will my photos be visible to other visitors?+
No. Move card photos are processed on your device. There is no public posting feed at present. You can save your card and share it on your preferred social platform.
