From Wikipedia, the free encyclopedia
The adidas 1 is a Trainer (more accurately, running shoe) made by adidas, introduced in early 2005. It is the first general consumer sneaker to incorporate a computer.
[edit] Technology
Requiring three years of development prior to release, the shoe adjusts itself after each stride, using a motor in the middle of the sole. The motor turns a screw, which in turn lengthens or shortens a cable, changing the compression characteristics of the heel pad.
The shoe typically runs at $250 in the U.S.
The changes are guided by a sensor in the heel, which determines how much the heel is compressed on each stride.
The shoe is battery-powered, and lasts for approximately 100 hours of running.

On 25 November 2005, Adidas released a new version of the Adidas 1.
There is an increased range of cushioning and a new motor with 153% more torque in the IL 1.1 upgrade.
