1950s ostrich hand lasted two-tone sling back shoes 7

True vintage 1950s. Well-constructed hand lasted ostrich and leather shoes with adjustable sling back straps. Leather soles. I had new heel tips put on a long time ago and then didn’t wear them more than a few times. The white ostrich leather and the smooth brown leather are in very good vintage condition. Wear does show on the insole and a bit on the white back of the shoe above the heel and on the end of the strap. (See last two photos.) Heel is 3.5”. Shown on my foot which is 3 1/4” wide and 9 1/4” long. From a smoke free and pet free home.
