In modern fashion, the terms clogs and mules are often used interchangeably, but there are some slight differences between the two. Women’s clogs originated in Scandinavia and the Netherlands as backless shoes with leather upper covers and heavy materials for the sole and heel.
Men's and women’s mules date back to Ancient Rome and were worn by the aristocracy. They were considered dressier shoes with open backs and soft fabric covers—sort of like ultra-fancy house slippers. Both mules and clogs have evolved over time, but the basic concepts remain unchanged. Clogs are best known for comfort and support, while mules are their dressier cousin.
