So what does a carbon plate actually do?
CRBN is being developed around a shaped carbon-fibre plate at the base of the insole. Supporting materials complete the design for compatible footwear. Performance benefits are not yet validated.
Carbon fibre, in plain English
Structure starts with the plate.
Carbon fibre uses strands of carbon woven and set in resin. CRBN’s design uses a 3K twill plate beneath the supporting layers. Plate shape, cushioning and footwear fit all matter; material choice alone does not establish a performance improvement.

Design intent and footwear fit.
For athletes
Carbon structure
A carbon-fibre plate forms the base of the insole, beneath its supporting layers.
Plate geometry
The shaped profile is part of the design, alongside the cushioning and arch components.
Multiple disciplines
Running and hybrid training lead the development focus, with court and field sports as potential applications.
For compatible footwear
Footwear compatibility
Check the space available inside your shoe rather than assuming every pair will fit.
Installation
Place CRBN where your original insole sits and follow the fit guidance.
Fit checks
Check toe room and heel hold after installation and whenever you move the insole between shoes.
What we're honest about
Intended applications. Not validated outcomes.
An insert is not equivalent to an integrated carbon-plated racing shoe. Footwear is a system of materials, geometry and fit. CRBN is developing a carbon-structured insole for compatible shoes, not promising the same performance as a racing shoe.
Running, hybrid training, court sports and field sports are intended applications, not sport-specific approvals. CRBN is under development and has not been tested or approved for every sport. Benefits in speed, jumping, endurance, injury prevention or energy return have not been validated.
