We founded our business with the goal of providing high-quality carbon fibre insoles, boosting performance for athletes. We aimed to do this at an affordable price, without compromising on quality. We work directly with manufacturers and experts to develop our custom CRBN insoles. We don't dropship, and never will. We believe in our product fully, and are proud to have been endorsed by athletes, experts, and industry professionals. 

We built CRBN by working directly with certified pedorthists and manufacturers. We don't compromise on quality.

In particular, we built CRBN insoles directly with Karl Kang. Kang is certified by the American Board for Certification in Orthotics and Prosthetics. He holds a current certification as a pedorthist, with certification number #4290. He graduated from the M.D. Institute of Biomechanics in Indiana, USA.
​
Pedorthist Kang has over 25 years of experience in designing quality insoles, and gives his full endorsement of CRBN insoles' benefits for both performance and support of athletic movement. We are proud to have worked with and received support from experts including registered pedorthist Kang.

​Becoming an ABC Certified Pedorthist is a desirable certification, confirming a healthcare professional's specific education and training to manage comprehensive pedorthic patient care. 

By working with Karl Kang, we were able to develop insoles which our customers can trust; with ergonomic benefits, customised support, and proven benefits to performance.

Karl Kang offers his full support of CRBN's performance, including a tested average of two inches of added vertical.

We also take sustainability seriously- every parcel is shipped 100% carbon‑neutral through AusPost’s eco‑shipping network, backed by a growing fleet of electric vehicles, renewable energy use, and fully recyclable packaging. We believe your performance shouldn’t harm the planet.

We found many key benefits of using carbon fibre technology in the insole of shoes. To do this, we used published, peer-reviewed information and studies about carbon fibre insoles from multiple sources. Additionally, we worked with pedorthists and athletes to conduct testing.  Here's some of what we found:​

​

• Athletes using carbon insoles report a 20-30% decrease in the incidence of common sports-related injuries

• Average increase of 2-3 inches in their vertical jump height compared to standard insoles

• 25-30% decrease in peak impact forces, reducing the impact on lower limbs during jumps, landings, and quick direction changes inherent in basketball movements

• The rigidity of carbon insoles provides exceptional support for the arches and midfoot, enhancing overall stability and balance
