Consider Width
Chanel ballet flats are available in regular width (marked with just the size number, like 38) and medium width (marked with “C” and the size number, like 38C). The width marking appears on the sole or the box, so check carefully when shopping, as it’s not always apparent on the shoe itself.
If the regular width feels too snug, the C width gives you extra room without sizing up. Even if the length feels right, a narrow width can cause pinching. Keep in mind that the material of your Chanel ballet flats will also impact how they fit and feel.
