Shoe inserts that are washable and feel like slippers: Cut a more rigid shoe insert to fit in your shoes. Add a soft foam one on top for softness. Take a snug fitting ankle sock and starting at the toe, slide the sock over both inserts, tucking the open ankle part under the inserts heel. Washable inserts for these who like to go barefoot in their shoes. Buying a half size larger shoe will give you room for a double soft insert.
