Arched feet means that her feet are arched which is usually done to pose more sexy. This is usually not done barefoot but by wearing very high high heels or Fetish Shoes or Fuckme Shoes. Arched feet lead to the impression that her feet are shorter than they actually are and her legs much longer. Furthermore, arched feet create a space in between her shoes and her foot soles, which is of special interest for arched foot fetishists. Not many would consider flat feet sexy, but there are all types out there.
