Adidas's new bionic running shoes, named "1", is claimed to be the first mass-marketed shoe to contain electronics in it, more than just blinky lights. it has two buttons for harder/softer cushioning, a magnetic sensor to gauge the cushioning needed and relay the data to the microprocessor, and a drive train running from the motor makes adjustments. the funny part is, it comes with a cd-rom that just contains the instruction manual on how to change the battery after 100 hours.
