International footwear manufacturing company Nike withdrew a shoe displaying an early version of the American flag after former NFL quarterback Colin Kaepernick warned the design was associated with slavery, the United States media reported on Monday.

Known as the Betsy Ross flag, Nike had unveiled the Air Max 1 USA featuring an American Revolution-era design imprinted on its heel to coincide with the United States’ July 4 independence day.

The Wall Street Journal reported that Nike pulled the shoe following dissents from Kaepernick, a Nike endorser who led kneeling protests during the national anthems of NFL games in 2016 to protest racial inequality and social injustice.

Kaepernick said the design featuring 13 white stars in a circle was offensive because it was associated with a period of slavery, which was legal in the U.S. after independence from Britain. White supremacist groups hostile to diversity have also recently appropriated the design, the newspaper said.

Nike shipped the shoes to retailers but then asked for them back, and had taken the design off its website, the Journal reported.

"Nike has chosen not to release the Air Max 1 Quick Strike Fourth of July as it featured the old version of the American flag," a Nike spokesman told the Journal.

The price of a few pairs available on an online shoe reseller rose to as much as $2,000 following the publication of the Journal's article, the newspaper said.

Kaepernick and former San Francisco 49ers safety Eric Reid settled collusion lawsuits against the NFL earlier this year for less than $10 million over claims team owners had plotted to keep them from playing.
