The Guilles have run their hosiery factory for over a century, at Briatexte, a small village in the southwest of France. In 1947, Robert created the Collégien brand and, with his brother Alain, invented the injection of a soft rubber sole in a sock: the slipper-sock was born! In 2007, Olivier Guille, today’s CEO and the founder’s great-grandchild, restyled this iconic item and made it a worldwide beloved accessory, thank to its design, vivid colours and comfort.
