Bruno Magli Black Soft Leather Ballet Square toe Flats Size 10 but fit 9

The leather on the shoes is so soft. A very on trend style Minimal wear and cleaned. Treated with leather care product. They are second hand to me so I do not know the origins. There is a very slight residue on the inner heels where a cushion was placed I hoped they would work for me but I cannot fit my orthotic in them
