Shoe Last
The three-dimensional solid form — traditionally wooden, now often plastic or digital — around which a shoe is constructed, whose shape determines the internal geometry of the footwear and its compatibility with orthotic insoles.
Full Definition
A shoe last is the foot-shaped mould used in footwear manufacturing to define the internal volume, toe box width, heel counter geometry, and overall fit of a shoe. In orthotic practice, the last is critically important because the internal shape of a shoe must accommodate an orthotic device without compromising fit or function. Orthotists and orthopaedic footwear specialists must communicate last specifications — including last width, heel-to-ball length, and toe spring — when prescribing orthotic-compatible footwear. The term 'last' should not be confused with the shoe's 'upper' or 'insole board'. In digital workflows, a virtual last is used in CAD/CAM footwear design.
Usage
Usage note: The word 'last' in this context is a noun meaning a shoemaker's form; editors must not mistake it for the common adjective meaning 'final'. Context within orthotic footwear documentation disambiguates the meaning.
