Is it OK to play Pickleball barefoot?

A variation of Tennis called Pickleball is becoming the latest "in"sport,although Ive never played it as yet.I know a person who has a regulation court and shes invited me to play with her.The only sport shoes I have are a pair of high-top tennis shoes which the person advised against wearing because she says they tend to be too bulky and cumbersome for the game;she also says they might leave scuff marks on the court.This person has told me that they do make regulation "pickleball"shoes,but frankly I have no intention of buying something for a sport Ive never tried before.Ive explained all of this to her,and she insists that I can simply go in bare feet on the court;that theres not any danger or harm from doing so.Is she right?
