Vintage Burgundy Mary Jane Heels

Timeless vintage Mary Janes in a burgundy/brown shade. It looks and feels like leather, but no material ID. Also no size ID. The shoe is just under 10.5”, which corresponds to a US size 11, BUT I wore them as a size 8.5-9 and appreciated the room in the toe box for comfort, so I have them listed as a size 10 to put the difference (sorry if you came here and they won’t work for you!). Good vintage condition. Some leather is worn off at the buckle but the rest of the shoe is in very good condition at the heels and toes.
