Adidas F50 TUNiT FG — "USA WC26"
The legend returns for the biggest stage. The Adidas F50 TUNiT "USA WC26" is a 2026 FIFA World Cup tribute edition of one of the most iconic and technically innovative boots in football history — the F50 TUNiT. Originally released in 2004–2006, the TUNiT system revolutionised the boot market with its groundbreaking modular design: interchangeable uppers, soleplates, and insoles that allowed players to customise their boot for any surface or condition.
The USA WC26 colourway celebrates the United States as a co-host of the 2026 FIFA World Cup alongside Canada and Mexico — the most commercially significant World Cup in history, played across 16 cities in three nations. Red, White, and Blue — the Stars and Stripes on the world's greatest stage, as the USMNT steps into the spotlight on home soil.
Brand new. A collector's piece that bridges football heritage and the 2026 World Cup moment.

Nike: Generally true to size. Older silos (T90, CTR360) run narrow — go half size up if wide footed.
Adidas Predator (2008–2016): Tend to run half a size large.
Copa Mundial: Leather stretches — if between sizes, go smaller.
