It is not permissible for women to wear shoes that look like men’s shoes
Question

                Recently there have appeared in the marketplace women's shoes which from the front look like men’s shoes, sandals with a separate space for the big toe, but from the back and the bottom they look like women's shoes. Is it permissible to buy them and wear them?
Praise be to Allah.If 
          they look like men’s shoes, and if a person sees them he will think 
          that they are men’s shoes, then it is not permissible for women to wear 
          them. Similarly, if a man were to find shoes which looked like women’s 
          shoes although the soles and heels looked like men’s shoes, it would 
          not be permissible for him to wear them, because what counts is the 
          way things look. My advice to my sisters is not to wear them, because 
          this is a serious matter. It was reported that the Prophet  
          (peace and blessings of Allaah be upon him) cursed men who imitate women 
          and women who imitate men.
