A petition on the site Care2 asking Adidas to drop its partnership with West "and tell the world they do not want anything to do with anyone who believes that millions of Africans chose to toil the fields in bondage for 400 years" has garnered more than 25,304 signatures.
Adidas executives have remained silent on the controversy thus far.
The German sportswear giant West last year announced an expansion of its relationship with the music and fashion icon and is developing a Yeezy-branded entity creating footwear, apparel and accessories for all genders across street and sport.
By contrast, Nike CEO Mark Parker is believed to have apologised for the company's culture and promised improvements, which have begun with the elevation of several executives, including women, presumably in a desire to take action after evidence that many complaints to human resources went ignored.
