Pies Descalzos later sold over 5 million copies, prompting the release of a remix album, simply titled The Remixes.

It has since sold over 7 million copies worldwide and 1.5 million copies in the U.S. alone, making it one of the best selling Spanish albums in the U.S. Eight singles were taken from the album including "Ciega, Sordomuda", "Moscas En La Casa", and "No Creo", which became her first single to chart on the U.S. Billboard Billboard Hot 100, "Inevitable", "Tú", "Si Te Vas", "Octavo día", and "Ojos Así".
