Adidas adizero F50 XTRX SG SYN UK6.5

Original Adidas adizero F50

The Adidas Adizero F50 XTRX SG SYN is renowned for its ultra-lightweight design, aimed at enhancing player speed and agility on the pitch. The 2014 edition of the F50 Adizero saw significant improvements, particularly in the synthetic upper, which transitioned from the single-layer SprintSkin to a combination of two new materials: HybridTouch and SpeedFoil. HybridTouch is utilized in the tongue and front part of the upper for its thin, yet soft and flexible properties, while SpeedFoil in the rear part of the upper focuses on lightweight durability and support. This blend of materials aims to provide an almost seamless integration for improved performance​
​.

Comfort and fit have been consistent highlights of the Adizero F50 series, with the 2015 edition maintaining a snug, barefoot-like sensation, thanks to the HybridTouch synthetic upper. The fit is slightly wider compared to previous models, accommodating a broader range of foot shapes without being too narrow. The introduction of a single set of improved comfort insoles, featuring denser foam and synthetic suede lining, further enhances the in-boot experience, ensuring comfort from the first wear​
​.

However, one of the most surprising changes in the 2015 model is the increase in weight to 7.1oz, which, while still light, marks a noticeable shift from the line's traditionally weightless feel. This change is attributed to the new soleplate design, which replaces the hard plastic SprintFrame with a thicker, more flexible plastic material, offering a more solid and natural feel underfoot. Despite this, the boot remains competitive in the lightweight category, albeit not as featherlight as its predecessors​
​.

Traction has also seen a major overhaul in the 2015 model, with a more aggressive stud pattern inspired by sprinter's spikes, aimed at maximizing acceleration traction. The heel features three studs, while the forefoot adopts a new layout for improved ground penetration and stability on various natural grass surfaces​
​.

Overall, the Adidas Adizero F50 XTRX SG SYN continues to evolve, balancing the need for speed with comfort and stability, making it a compelling choice for players seeking a lightweight boot that does not compromise on performance features.
