It seems you're referring to the shoes from the 2006 film "The Devil Wears Prada" starring Anne Hathaway as Miranda Priestly's personal assistant Andy Sachs and Meryl Streep as Miranda Priestly. In the movie, Miranda Priestly is seen wearing Valentino shoes.
However, I couldn't find any information on a sequel titled "The Devil Wears Prada 2" or any official announcement about a sequel to the film.
