Germanys team wears mostly adidas boots, and is team-sponsored by adidas. Nike is brazils team sponsor and most brazil players have nike boots on. I think nike is in a horrible spot right now with their ridiculous 275 dollar boots that could now be construed as inferior shoes to adidas's because of the colossal disaster of the bra ger match.
Also the multi million dollar animated commercial nike paid for is just stupid, while adidas's is just awesome.
Moreover adidas has messi and nike has crying diving ronaldo
