The Papal slippers () are a historical accoutrement worn by the Pope. The papal slippers were a form of episcopal sandals worn by bishops. However, unlike the (rarely seen) episcopal sandals, which change with the liturgical colour, the papal slippers were always red.
Usually elaborate, papal slippers were made by hand with red satin, red silk, and gold thread; they featured an embroidered cross garnished with rubies and the soles were made of leather. Until the first half of the 20th century, it was customary for pilgrims having an audience with the Pope to kneel and kiss one of his slippers.
