Adidas F50 Adizero TRX FG Messi Running White/Black/Solar Slime

The Adidas F50 adiZero TRX FG Messi in White, Black and Slime is the "Fast or Fail" colorway, released March 4, 2014 — Messi's own signature drop rather than the standard Battle Pack worn at that summer's World Cup. Instead of the pack's black-and-white split, this one runs a white base with Samba-inspired color dripping vertically down the sides in orange, pink, blue and green, a bright green "Solar Slime" soleplate with pink studs, and Messi's "M" emblem on the heel in black.

The upper is made entirely from HybridTouch synthetic. At the time, Messi's boots had always skipped the SpeedFoil heel panel other F50 adiZero colorways used, for a more consistent feel across the whole foot. It sits on Adidas's SprintFrame outsole, tuned for acceleration and quick direction changes on firm ground.

This pair is a US 9, brand new in original box, with replacement insoles included. Runs true to size but snug — a tight, locked-in fit that suits average-to-narrow feet best, with some initial tightness through the first couple of wears before the upper eases in.
