For most of history, shoemaking has been a handicraft, limited to time-consuming manufacturing by hand. Traditional shoemakers used more than 15 different techniques for making shoes, including pegged construction, English welted (machine-made versions are referred to as "Goodyear welted" after the inventor of the technique), goyser welted, Norwegian, stitch down, turnout, German sewn, moccasin, bolognese stitched, and blake-stitched.
The traditional shoemaker would measure the feet and cut out upper leathers according to the required size. These parts were fitted and stitched together. The sole was next assembled, consisting of a pair of inner soles of soft leather, a pair of outer soles of firmer texture, a pair of welts or bands about one inch broad, of flexible leather, and lifts and top-pieces for the heels. The insole was then attached to a last made of wood, which was used to form the shoe. Some lasts were straight, while curved lasts came in pairs: one for left shoes, the other for right shoes. The 'lasting' procedure then secured the leather upper to the sole with tacks. The soles were then hammered into shape; the heel lifts were then attached with wooden pegs and the worn out-sole was nailed down to the lifts. The finishing operation included paring, rasping, scraping, smoothing, blacking, and burnishing the edges of soles and heels, scraping, sand-papering, and burnishing the soles, withdrawing the lasts, and cleaning out any pegs which may have pierced through the inner sole.[5]
Until the 19th century, shoemaking was a traditional handicraft, but by the century's end, the process had been almost completely mechanized, with production occurring in large factories. Despite the obvious economic gains of mass production, the factory system produced shoes without the individual differentiation that the traditional shoemaker was able to provide.
Similar exigencies at the time of the Crimean War stimulated a renewed interest in methods of mechanization and mass-production, which proved longer-lasting.[6] A shoemaker in Leicester, Tomas Crick, patented the design for a riveting machine in 1853. His machine used an iron plate to push iron rivets into the sole. The process greatly increased the speed and efficiency of production. He also introduced the use of steam-powered rolling-machines for hardening leather and cutting-machines, in the mid-1850s.[8]
Traditional shoemakers still exist today, especially in poorer parts of the world, and create custom shoes. Current crafters, in developing regions or supply constrained areas may use surplus car or truck tire tread sections as an inexpensive and plentiful material resource with which to make strong soles for shoes or sandals. Generally, the modern machinery used includes die cutting tools to cut the shapes and grommet machines to punch holes for lacing.
