Sandals by Salvatore Ferragamo at the Metropolitan Museum of Art. I would have guessed they were from the 1960s, but no! 1938! Signore Ferragamo was ahead of his time. Or were the 60s a flashback?

Sandals from the Metropolitan Museum of Art, Gift of Salvatore Ferragamo, 1973

Your sketch was good. Beautiful shoes, but I don’t know how anyone could safely wear them. I once saw a model fall twice wearing shoes something like that. 🙂
Hazardous duty, to be sure.
