The Adidas 1, intelligence level 1.1, shoe uses a sensor, a microprocessor and a motorized cable system to automatically adjust the shoes’ cushioning. This is how it works: a sensor under the heel measures compression and decides if the shoe is too soft or firm. This info goes to the microprocessor and adjusts the heel cushion while the shoe is in the air. A recent new update even increases the range of cushioning, meaning the shoe can become even softer or firmer. The new Adidas 1, intelligence level 1.1, is available in a range of colors, and sells for $250.
