In the Spanish language, especially in countries like Spain, this style is known as merceditas. The term originated in Spain in the year 1878.
Queen María de las Mercedes of Orleans, commonly known as “Merceditas,” married King Alfonso XII, creating one of the most iconic love stories in the history of the Spanish royal dynasties. Their romance was intense but also very brief, as just five months after their marriage, Merceditas fell ill and died. Interestingly, a song was dedicated to her referencing this type of shoe, the merceditas, as it was one of the wedding gifts Alfonso gave his wife.
