I think these are Ferragamo's own reproductions, either contemporary (modern) or from the 2000-2010, because I remember somewhere in there being a revival of the babydoll shoe style. I know I bought some new shoes that would pass for 1950's around that time.
My mid 1950's Ferragamo's have handwritten manufacturer's numbers and details inside, not printed, leather soles and heel tips. It would help to see photos of the soles and heel tips but I think your tips may be plastic.
