The store adopted the motto "Still Choosing to Stand, Just Doing It", referencing Kapernick's decision to kneel during the National Anthem.
During the summer, Nike revealed that Colin Kaepernick would be the face of one of their biggest campaigns of all time.
The NFL player, who controversially chose to kneel during the National Anthem to protest police brutality, was made the face of the 30-year anniversary of Nike's 'Just Do It' campaign.
The campaign was unveiled, accompanied by the caption: "Believe in something. Even if it means sacrificing everything."
Following the release of the initial ad, people began to boycott Nike products in protest with some even going as far as burning Nike clothing... which they'd already bought.
And it looks like the boycott had an effect, just not necessarily the one that they had been hoping for.
A sports shop in Colorado, America has closed down, following a boycott of Nike goods.
Owner of Prime Time Sports, Stephen Martin, posted on Facebook on Monday announcing a closeout sale with all merchandise marked 40 percent off.
"Thank You for 21 mostly good years. For everybody that has offered help and support through the "Honor The Flag" memorial wall and NIKE boycott, now is your time to help me liquidate."
Kapernick is still without a club in the NFL, which many believe to be due to the controversy that would follow him if he were to sign for a team.
