Open toe describes a shoe, especially a sandal, which is not closed at the front, allowing the toes to be seen. Some open toe styles, such as peep toe pumps, have an enclosed vamp with a small opening at the toe, which make them more suitable for formal wear during warmer weather.
About Platform Shoes:
Platform shoes are shoes with a thick, raised outsole where both the heel and the toes are raised, thus providing height to the wearer. Platform shoes may also have an elevated toe area with a separate heel.
