The Leather upper on the Adizero was introduced in 2010 and was the thinnest, and lightest technology available for the time
Adidas used a Goleo Calfskin Leather, which was used on all the leather Adizero's
With a K Leather like feel, but a super lightweight design, the Calfskin Leather proved to be a favorite for the Adizero line
This 2011 edition wasn't much of a difference from the previous model, aside from a new paint design
The Sole Plate:
An almost identical sole plate was used from the original Adizero
The same triangular shaped stud patter was used, in a durable and lightweight hard plastic bottom
This 2011 model also featured the "MiCoach" technology, which allowed you to insert a chip in the sole plate and track your movements via the MiCoach software
