Jazz shoes should fit you perfectly. You don’t want to get them too loose or too tight.  Jazz shoes usually come in black and tan colors.  You will find good quality jazz shoes at a dance store. 

For jazz you need to be stretched and warmed up.  Jazz is a high pace workout.  So if you don’t warm up or strength you will get hurt or pull something.
