The Upper: A lightweight synthetic upper with a dimpled texture was used throughout, its similar to the Hypervenom Phantom design, but much smaller grooves The boots featured a Messi decal logo near the toe box  The upper features a "cage" element towards the back, which is a rubber heel material, designed to help with a more locked down fit The Sole Plate: The stud designs are very similar to the previous Adizero models, but with some slight changes The front and back studs feature a circular like cut, a spec that is commonly used on Messi's specs but was never used on retail models until now The sole plate features a series of diagonal plastic elements for the "spine" of the sole plate Notes and Comments: The Messi model was short lived by Adidas Overall, the upper wasn't anything too revolutionary, and the cage system didn't add much to the boots The sole plate was closely designed to the same specs Messi actually uses, which was an upgrade from the F50 Adizero
