Adidas is the 2nd biggest sports brand in the world, almost feels like it doesn’t count lol

Also:

• Puma (German)
• Lacoste (French)
• H&M (Swedish)
• Primark (Irish)
• Ellesse (Italian, owned by the British)

Also there’s Fred Perry and Fila which are both Asian-owned (by Japan and South Korea respectively), but they’re at least nominally European brands.

Some European brands are American-owned though, like Umbro and Reebok.
