Prada black patent platform sandals with buckle accent

Used Prada platform sandals in need of repair. These are the cutest shoes but need help. I had purchased these used and saw that the cork was breaking off on the underside of the shoes. I sealed them with a cork sealant, which has helped stop the progression. However, the right shoe insole is becoming detached and needs to be glued or reattached by a cobbler. Also the sole on the left shoe bottom has detached. Not sure if a cobbler will glue it or reattach by another means. 4 inch heel. I cannot wear heels this high anymore.
