40s/50s style shoes

These sandals are a typical 40s / 50s design.
They are a two tone off white . They are in a leather type material but I cannot say they are leather for sure.

They have a supportive wedge.
The insoles are starting to lift away from the soles at the side.
The sandals do have some signs of wear but are still a good pair of original shoes. They could do with a good clean
They are stamped with size 6 1/2
