Adidas 1 Sneaker

Brand new and have never been worn Adidas_1- Worlds First Smart shoe Collectors Item Mens size 9 Requiring three years of development prior to release, the shoe adjusted itself after four strikes stride, using a motor in the middle of the sole. The motor turned a screw, which in turn lengthened or shortens a cable, changing the compression characteristics of the heel pad. The shoe typically costs $250 in the U.S at launch. The changes were guided by a sensor in the heel, which determined how much the heel was compressed on each stride. The shoe was battery-powered, and lasted for approximately 100 hours of running.
