My teacher HACKS consist of buying youth TOMS. For example, (I do not have dainty, petite feet) I wear a size 9 in women TOMS and I wear a youth size 6. The reason, I like buying youth is because they are CHEAPER, have more CUSHION and there are so many PATTERNS you can choose from!!
If my wide, solid caveman feet can fit into a youth TOMS... consider trying them on!!!
