Adidas is set to launch the world first performance laceless basketball shoe,the Adidas T-MAC 4 with HUG Systems Technology on October 29£¬2004. The Adidas T-MAC 4 features a revolutionary closure system that locks the foot securely in place, providing superior comfort and fit. The process that has led to the HUG Systems Technology began in early 2001 in the office and laboratories of the Adidas Innovation Team.The HUG Systems Technology idea came from the closure system of a ski boot. The HUG element fits over the top of the area of the foot.This is attached to the rear of the shoe by cables that put the element under tension, which is maintained by a closure device on the heel counter. The closure device, a slider/lever system is used to control the fit. Turning the adjustment wheel moves the slider up and down on the thread, giving the athlete the most precise fit possible.
