The president's son posted his own version of the ad on Instagram Wednesday with the comment, "There, fixed it for you".
Online, people threatened boycotts and posted videos and photos of shoes set on fire, Nike gear thrown in the trash, and swoosh logos cut out of products.
"Believe in something, even if it means sacrificing everything".
The ad stood out as a bold statement on racial justice from Nike and as the latest demonstration of the company's values, experts said. "If Nike is ashamed of America, we are ashamed of them". "I have said that since Day 1".
The ad includes footage of Davies scoring a goal for Canada's men's soccer team as Kaepernick says "if you're born a refugee, don't let it stop you from playing soccer for the national team at age 16".
"I think it's a bad message that they're sending and the objective of them doing it, maybe there's a reason for them doing it", Trump said in an interview with the Daily Caller.
In announcing the deal, Nike said he was "one of the most inspirational athletes of this generation".
However, Williams added that athletes needed to be careful of how they participate in any sort of social injustice.

But I just had a feeling we could spark it and get things going, and we just put together a couple drives. "This will definitely go down as one my favorite memories, especially in this rivalry", Rodgers said.
The tweet inspired more players to kneel, which revived the issue between the players and their rights within the NFL.
Newton said last season he thought the way Kaepernick has been treated was, "unfair", and when asked his thoughts on the new Nike campaign, Newton doubled down in his support.
But Nike's ad "wades into different water", Grier said.
After his protests, Kaepernick could not find a job for the 2017 season and sued the National Football League, accusing owners of colluding to blackball him.
The advert, titled "Dream Crazy", has Kaepernick narrating over images and footage of various athletes with inspirational stories, including National Basketball Association icon LeBron James, tennis star Serena Williams and Kenyan runner Eliud Kipchoge.
But to one fellow member of the pro-quarterback fraternity, an athlete's sacrifice - even one that could mean no longer being a professional athlete - doesn't compare to some more real-world examples. "As for me, I support Colin, I support my brother, I support the stance that he's taking".
Newton said Kaepernick has his respect.
The ad is also expected to air this week during college football and Major League Baseball games, and stream on various music, gaming and other platforms, Nike spokeswoman Sandra Carreon-John said.
