Since then they have turned a popular form of footwear into a sophisticated product closely associated with design and fashion. Their encounter with Yves Saint Laurent in the 1970s went down in the history of world fashion and together they created the first wedge espadrille. Today, after 90 years, their product has a worldwide reach but their essence remains as authentic as it was in 1927: tradition craftsmanship and natural materials.
