A Special Kind of Shoe The Netherlands is a country in Europe known for its tulips, its cheese, and its unique wooden shoes called clogs. Although clogs are not worn as often as they once were, farmers in rural parts of the Netherlands still wear these shoes. Clogs make walking on muddy soil much easier. They also protect a person's feet from heavy and sharp objects as well as potent acids.

Traditionally, clogs were made by hand from poplar and willow. Cobblers could carve seven pairs of clogs each day, and this process included hand painting the shoes. Today, clogs are assembled by machines most of the time. However, one factory near Amsterdam still has workers who carve the shoes by hand.
