Developed in collaboration with marathon runners, this exclusive carbon fiber composite formula boasts the industry's lightest density at 2mm thickness (1mm carbon fiber + 1mm foam), making it lighter and more supportive than existing carbon fiber insoles on the market. Installation is effortless, requiring only the removal of the double-sided adhesive film from the foam side and placing it between the original insole and midsole of your shoe, ensuring a seamless and comfortable fit with no discomfort. The slight arch support provides a sensation akin to having an internal springboard, delivering a pronounced sense of speed and propulsion with every stride. Major footwear manufacturers have already integrated carbon fiber plates into their insoles, resulting in enhanced propulsion with each step when running.

Moreover, this technology is also suitable for golfers. During the weight shift in the swing transition, the carbon fiber insole enables the right foot to exert more power during rotation and pushing off.
