Mexican-American clothing designer Willy Chavarria has apologized for an Adidas sandal that he created after being accused by Mexican authorities of "cultural appropriation" for copying an indigenous shoe design. The design launched by Adidas is known as the Oaxaca Slip On." It's a black sandal with braided leather straps attached to a chunky sports shoe sole. Mexican artisans and authorities say the intricate leather braids look strikingly similar to the traditional footwear known as huaraches made by the Zapotec Indigenous people in Oaxaca. Chavarria responded to mounting criticisms in a statement addressed to the "people of Oaxaca" in comments sent to The Associated Press on Tuesday. He said that "I am deeply sorry."
