What do I do if I have one foot bigger than the other?

It is of paramount importance to fit each foot individually and sometime a dancer will require two pairs of shoes.
However, that is not a problem, because pointe shoes do not have a right or left foot. So, it means that you will have two shoes which you will only wear on the right foot and two shoes which you will only wear on the left foot. Mark both shoes as R or L and split them into your special pair. Now mark the pairs as 1 and 2. When you first start with pointe work your feet might change shape, therefore it is really important that you wear both pairs equally, and rotate the pairs with each class. This means all the shoes change shape at the same time and follow the progress of your feet equally.
