Collegien is a French accessories brand established in 1947 by Robert Guilles. Robert and his brother Alain invented the injection of a soft rubber sole in a sock, which lead to the slipper-sock. Six decades later the founder's great grandson and CEO, Olivier Guilles, restyled the iconic item and made it a beloved accessory.
In addition to the slipper-sock, Collegien offers socks, tights and knitted accessories for the whole family. They create styles from current modern trends and control all their manufacturing processes in France. Materials used include long-staple Egyptian cotton, cashmere, silk and extra-soft lurex.
