I assume for school you are required to have white shoes? Depending on your budget, there is a large variety of white sport, exercise, and walking shoes to choose from. I like a shoe that securely ties. I have a pair of SAS, San Antonio Shoe Co., shoes that are designed as walkers that I quite like, for instance. After all, I walk all night, eh? I don't wear them much now, because white is impractical in my opinion.
