Cleat Material Developed for Ball Control Can Repair Colon

Microscopic pillars on the Nanostrike+ fabric of Adidas Predator cleats, designed by University of Illinois Urbana-Champaign mechanical engineering professor Bill King, enhance ball control for soccer players. This friction-engineered surface mesh provides a consistent grip, activating increased force and spin when a player strikes the ball. The technology was initially developed for electronics fabrication and micromechanical devices, with the goal of scaling microstructures for consumer products.

King's research, which began 20 years ago, was inspired by the grip of insect feet. The aim was to engineer a surface that was both water-repellent and grippy, mimicking insect tarsus spines. Early applications focused on micro-assembled electromechanical equipment for the Department of Defense and microstructures for engines and pumps for the Department of Energy. In 2006, King collaborated with Ralph Hulseman, then an engineer at Michelin, leading to the founding of Hoowaki to commercialize the technology.

Hoowaki has since developed over 800 micro-patterns and now offers materials capable of gripping various surfaces. Beyond sports applications, the company produces medical devices, including a tube designed to eliminate the need for stitches after esophagus surgery. Crucially, this same material technology has demonstrated the ability to repair the colon, showcasing a significant pivot from athletic performance to critical medical interventions.
