So cute!!  Vintage late 60's / early 70's   Shiny white with black scroll trim chunky heel shoes.   These are UNWORN and include the original box !      Size on these is 4.5 M.     Please check the measurements below:

Width at ball of foot - 2.75"
Heel Height - 2"
Sole length measured on the inside of the shoe - 8.5" 

I wear a size seven medium width and tried these.  Waaay to small for me, so I believe the 4.5 is probably true to size.
