Roberto Vianni leather shoes

Very gently worn Roberto Vianni leather upper dark grey dress shoes. As seen in the photos, these shoes are a bit of a chameleon and can co-ordinate with many colours. In certain light, they have a dark brown tone, in others, almost black. They have elastic extensions on both sides to give added comfort, as well as super cushioned insoles. Unfortunately there are no size indicators, but I wear a size 8 and these are just a bit snug, but I could wear them for a couple of hours. 2 1/2” heel.
