The Guilles have been running their hosiery factory for over a century, in Briatexte, a small village in southwestern France. In 1947, Robert created the Collégien brand and, together with his brother Alain, invented the combination of a soft rubber sole and a sock: the slipper-sock was born! In 2007, Olivier Guille, the current CEO and great-grandson of the founder, reshaped this iconic product and made it a globally beloved accessory, thanks to its design, vibrant colors and comfort.
