The mountainous areas of Northern Spain (Galicia, Asturias, Catabria and the Basque Country) and Castilla and Leon, Aragon and Catalonia, have a humid climate with a lot of rain which makes roads and fields very muddy. Traditional footwear local to these regions include madreñas which are wooden over shoes. Soles include added blocks to lift the feet from the mud. The shoes were made locally by village craftsmen and are highly decorated with carvings or painting. The design is usually different for men and women.
Madreñas are similar to Dutch and Sweden clogs and made from a single piece of wood of green alder, beech, walnut or less often brown poplar.
