Shoe technology is a little noticed field of development, but it brings in a lot of cash. Just ask Nike or Adidas. Dedicated customers will line up for each new shoe offering, and athletes follow shoe trends on the belief that they can help boost performance.Nike is just about ready to release the granddaddy of futuristic shoe concepts. Think pretty much Marty McFly’s power-laces from Back to the Future: Part II. The company has just announced that its self-lacing shoes will be available soon.
