Turn any shoe
into a
super shoe.

Performance you install.

Carbon-structured support, designed for running, hybrid training and dynamic movement inside compatible shoes you already own.

Shop CRBN Discover the technology

Keep the shoes.
Upgrade what's inside.

Performance shouldn't require another pair of shoes. CRBN is being developed for athletes who run, train, jump and change direction, with carbon-fibre structure inside compatible footwear.

Install it. Move it. Take it with you.

The proposition

What makes it super?

Carbon support

A carbon-fibre plate sits at the base of the insert, forming a structured platform beneath the cushioning layers.

Stability

A deep heel cup and dynamic arch are designed to provide a structured fit underfoot.

Responsive design

Designed around plate geometry and supporting materials; performance benefits are not yet validated.

Performance you install

Not a shoe you replace.

A carbon-structured base, a stable platform underfoot and a lightweight build, all inside the shoes you already own. Cleaner, smarter and more versatile than buying a new pair every time.
