In some parts of Europe clogs are still worn, although mainly in costume roles. Until fairly recently clogs were worn daily by crew on steam engines and in some factories in England (the north, usually), as it made sense not to wear leather footwear with the possibility of tools falling on feet. Blades would go straight through leather, whereas wooden clogs saved lives. These days workmen's boots are fitted with steel toecaps to achieve the same end.
Morrismen around the south and south-west mostly, and Coconut/Clog Dancers in the north keep up a tradition, and in the Netherlands clogs are part of 'National Costume'.
