A last is a form in the approximate shape of a human foot, used by shoemakers and cordwainers in the manufacture and repair of shoes. Lasts typically come in pairs, and throughout their history have been made from many materials, including hardwoods, cast iron, and, more recently, high density plastics.
Lasts are made to varying degrees in the shape of the human foot, depending on their specific purpose. They come in many styles and sizes, depending on the exact job they are designed for. They range from simple one-size lasts used for repairing soles and heels, to hard-wearing lasts used in modern mass production, and to custom-made lasts used in the making of bespoke footwear.
Historically, lasts were made from a number of materials - typically hardwoods and cast iron. These are materials that will retain their shape, even when in contact with wet materials, like leather, being stretched and shaped.
The material used to make modern lasts must be strong enough to withstand the forces of mass production machinery, such as that applied by the pullover machines when bottoming the shoe, and must also be able to hold tacks (known as "lasting tacks") which are used to hold shoe parts together temporarily before the sole is added. Although hardwoods satisfy these criteria, modern lasts, especially those used by mass production factories in places such as China, are often made from high-density polyethylene plastic (HMW-HDPE), which allows for many tack holes before needing repair. Such plastics also have the benefit that they can be recycled and remoulded when they wear out.
A week is a time unit equal to seven days. The English word week continues an Old English wice, ultimately from a Common Germanic *wikōn-, from a root *wik- "turn, move, change". The Germanic word probably had a wider meaning prior to the adoption of the Roman calendar, perhaps "succession series", as suggested by Gothic wikō translating taxis "order" in Luke 1:8. The term "week" is sometimes expanded to refer to other time units comprising a few days. Such "weeks" of between four and ten days have been used historically in various places. Intervals longer than 10 days are not usually termed "weeks" as they are closer in length to the fortnight or the month than to the seven-day week.
Evidence of continuous use of a seven-day week appears with the Jews during the Babylonian Captivity of the 6th century BC. Both Judaism (based on the Creation narrative in the Bible) and ancient Babylonian religions used a seven-day week. Other cultures adopted the seven-day week at different times. Between the 1st and 3rd centuries the Roman Empire gradually replaced the eight-day Roman nundinal cycle with the seven-day week. Hindus may have adopted a seven-day week earlier than 11th century BC.[citation needed] See Rig Veda. There is evidence of some Chinese groups using a seven-day week as early as 4th century.
