Custom lasts

Cordwainers, or bespoke shoemakers, often use lasts that are specifically designed to the proportions of individual customers' feet. Made from various modern materials, they don't need to withstand the pressures of mass production machinery, but they must be able to handle constant tacking and pinning, and the wet environment associated with stretching and shaping materials such as leather.
