Dr. Scholl's "exercise" sandals... These were a hugely popular shoe fad of the 70s. Simply referred to by most as “Dr. Scholls”, this shoe was about as simple as they come. They had a wood sole formed into a shape that was designed to support the arch and raise the toes for a good grip. They had a leather strap that was available in tons of colors--You could buy them at the drugstore!
