Like-New Vintage GAP Black Mary Jane Shoes

Is your left foot smaller than your right foot? Like-new genuine GAP Black Mary Jane shoes, fits like size 5 on the left and a size 6 on the right. Leather upper with buckle closure. The right shoe insole was removed to prepare to put in an orthotic that was never actually put in, but it was thin so does not affect sizing. Like-new condition, made in Brazil. Left is just a tiny bit too small for me.
