Traditional Korean footwear is usually of a very high quality and intricately made with leather uppers and linings, a woven textile layer in between with turned stitchings. Sometimes the uppers are combined with silk. The uppers with the edges turned outside are handstitched to the insole and a middle-sole, after the middle-sole was already handstitched to the outersole. Sometimes the sole-edges are plastered white. On the above shoe triangular hobnails, five on each toe and heel, re-inforced the outersole. When executed all in white, they were worn on funerals, as the traditional colour of mourning in Korea like in many Asian countries is white. For centuries the Korean rural people wore "Nmakshin" or rain-shoe, a stilted boatshaped clog made of a single piece of wood and especially practical in wet or muddy conditions.
