Kratos Carbon Fiber Insoles backed by Science

Independent testing by Craig Norton, President of La Foot Plus, using his Optimal Performance Index System (OPIS), evaluated the performance of the Kratos Carbon Fiber Insole inside an ASICS Gel-Resolution X tennis shoe. The shoe was tested both in its original configuration and again with the Kratos Carbon Fiber Insole installed. The results were remarkable and measurable. Testing showed that the Kratos Carbon Fiber Insole increased midfoot stability by 22%, boosted vertical support by 20%, and enhanced energy transfer by an incredible 33%. So what does this mean for athletes and everyday users? Simply put—we can energize any shoe. By reinforcing the structural platform of the shoe, the Kratos Carbon Fiber Insole helps deliver greater stability, stronger support, and more efficient energy return with every step. The result is a shoe that feels more responsive, more powerful, and more stable—whether you're competing on the court or moving through everyday life. This is more than an improvement in footwear performance—it’s a groundbreaking advancement in how shoes work with the human body.
