Wow. What a find. This is one of the very first Keds shoe made by the U.S. Rubber Company.
Very heavily advertised, this style appears in ads from 1919.
The U.S. Rubber Company was a manufacturer of rubber soles to the footwear manufacturing trade. At the end of WWI they started to manufacture their own line of men’s, women’s and children’s canvas sport shoes.
The 1919 models:
(note the more bulbous toes on the womens’ styles)
Give way to the slightly curvier heel and pointier toes of the 1920 styles:
We expect that this is a 1920s style as it lacks the heavy sole and extremely high heel of men’s Edwardian styles. The perforations are more delicate than the stylings of that era as well.

Until we post photos of men’s 1920s shoes here’s a lovely set of pages showing the strange deco-ness of footwear styles of the Roaring Twenties:
