Mexico is looking for footwear giant Adidas to pony up after a Mexican-American designer working with the firm, Willy Chavarria, launched a shoe inspired by a traditional Indigenous sandal, authorities said on Friday.

Mexican authorities are accusing Adidas of plagiarizing artisans in southern Mexico a new sandal design appearing strikingly similar to the criss-crossed leather in indigenous footwear known as huaraches.

Mexican officials say sportswear giant took design idea from Indigenous community in country’s southern Oaxaca state.
