Comfortably! Here are some guidelines we suggest:
Shoes should have little to no growing room as this can lead to injury.
Ballet flats and jazz shoes should hug the foot and be on the snug side.
Hard soled shoes like character shoes, tap shoes, and ballroom shoes should be comfortable without any heel slipping.
IMPORTANT: Pointe shoes should only be fit by an experienced fitter. This is critical! Save your feet and be properly fitted.
