Superfit leather sandals

Size 24 leather Superfit sandals. Bought new with two soles, worn for a month last summer outdoors, show signs of use - slightly scratched leather on the heels and the insoles have a slightly bluish tint from the sandals themselves (natural color and crumbles in moisture, but I think it can be cleaned with acetone or a miracle sponge). The insole and leather are in very good condition, carefully washed and treated with Ecco leather lotion. Delivery is not included in the price.
