Magnetism

Magnets in your shoes?

You'd think these would be just great for climbing steel rooftops or scaling the Eiffel Tower.

Actually the magnets in the Adidas Intelligence 1.1 aren't there to help you stick to metal surfaces at all.

No, according to the cobbler, the shoe provides intelligent cushioning by automatically and continuously adjusting itself. It does so by sensing the cushioning level, using a sensor and a magnet.

It then understands whether the cushioning level is too soft or too firm via a small computer. It adapts with a motor-driven cable system to provide the correct cushioning throughout the run.

Scary.
