The Upper:
The Shift was based off the top model Air Zoom Total 90 Supremacy, an iconic 2000's T90 design
The shift featured the same cosmetic look to the top model but used different materials
The upper was a bit thicker and more cushioned than the top model, it also didn't have the same heel cup as the Supremacy
 
The Sole Plate:
A major upside to the Shift model is the same exact stud configuration to the Supremacy was used
For the most part, the sole plate was very similar, but a bit thinner than the top model
 
Notes and Comments:
The list of greats that wore this model goes on and on, Figo, Rooney, Fernando Torres, and many more
The ultimate power and comfort boots that will go down as one of the most reliable and comfortable boots of all time
