Got these shoes because i Am in nursing school and they require you to wear white shoes. These shoes are white full plastic non porous. They come in a plastic clear carrier they do not come too far up on your heel and they are exact to fit but not too tight. But if your like me who prefer to wear socks with there shoes probably best to just get a half size bigger i only stuck with tghese because they are very affordable and only will be wearing for now. They also do have a bit of a plastic small to them. Kind of strong at first but after a few wears itll dissipate
