Your at a shoe store and in your hands there are two shoes, Nike and Adidas. You don't know what to buy and end up buying a Puma. I will compare adidas with nike on three types of sports.
First, basketball.On team Nike we have Air Jordan. Air Jordan is a type of shoes, pants, and shirts in Nike. Michael Jordan had a contract with nike to make the Air Jordan and him to wear it. Nike is still making billions of dollars with the Air Jordan and is also sponsoring Stephen Curry.(Superstar)On Adidas Alec Burks is sponsored and is not that good. Adidas had literally given up basketball to nike.
Secondly, soccer.Nike has good player sponsorships and a good soccer shoe technic (mercurial). Nike is sponsoring Cristiano Ronaldo and made a type of equipment for Ronaldo called CR7 but almost no one wears it.Adidas is sponsoring Lionel Messi and the balls in the world cup making nike unable to use there balls in the world cup. Also Son is sponsored by adidas so adidas wins this round.
Finally, running. Adidas had been selected to have ultraboost 19 as one of the best running shoes but nike zoom X is now in the top tier.
It seems like the final winner is under armour.
I like both but I prefer adidas more.
