There is currently no timetable for when these may hit the market, but the patent shoes indicate that Nike is definitely working on the technology.
That means, you drag a switch, and tightens as if you just pull and tighten the laces classics. The switch activates a motor that rolls or place a spool of thread distributed throughout the shoe. When the coils of wire in the shoe tightens on the shaft supported by various rods.
Naturally, the system requires a source of food and to has a battery on board. However, the patent reveals that Nike has not decided there go with a USB or mini USB port to charge the shoe. It's writeen by shen206 on 08.28.
