Sling back shoes but sling doesn’t stay up
Size: 8.5, Color: Cognac Suede
Strap on shoe that is the sling back doesn’t stay on. Keeps sliding off. I bought in size 8.1/2 which I usually wear. Too big. So I exchanged for an 8. And same problem. Slung back strap isn’t tight enough and falls down. The style is really nice so I’m disappointed they didn’t work.
