Vintage 1940s Platform Peeptoe Black Slingback Suede Shoes from Palter DeLiso Inc New York City
On inner heel I find "Capri Last". Sold at Dayton Company, Minneapolis.
In 1937 Palter DeLiso invented the very first peep-toe slingback pump! Info courtesy of: https://shopthrilling. com/collections/soulrust/heritage Find out more at the link.
Size 6 1/2 AA - please compare these measurements to a heel that fits you well - I wear a 6 usually and these fit pretty well.
Measure just under 9 1/2" insole. 2" at inner heel. 2 3/4" at ball of foot. Heel is 3 3/4" tall.
Normal wear to insole and sole - dings and scrapes - the back of the shoe by the heel of the foot is particularly worn -on one heel the heel tip is missing some of the edge and the suede got scraped by the heel tip - see photos, use zoom.

This item is sold from an excellent, highly rated vintage boutique.
