"Adidas 1" is the product of three years. A secret made in Portland, Oregon.

It has a microprocessor in the bottom with a motor. From what I remember of gel shoes, that pumped. That doesn't make me feel good about it breaking...OOPS, new pair of shoes at a hefty tag.

Blending it's air cushion shoes with a computer chip that changes its padding amount to a runner's make and step.

Powered by a battery. It conserves power by changing settings while in the air of a runner's motion, going around resistance of ground impact.

Tag $250
