The Footwear Last
What is a shoe last? The last is the form used to define the shape of the shoe. The last is critical to the shape and function of your shoe. The footwear last used by the factory will decide the look, fit, and shape of the shoe. The right last can make your shoe a high fashion hit! The wrong last can make your design look like an ill-fitting brick. The Pattern Master creates the shoe pattern to fit the last tightly. Each different type of shoe will need its own specific shape of last. The last for a running shoe has a very different shape than a last used for a hiking boot or basketball shoe.
Last Shape, Fit, Performance, and Style
The last determines the shape, fit, performance, ergonomics, and style of a shoe. There are many different types of lasts. Lasts can be injection molded plastic, carved wood, or cast from aluminum. The last is the starting point of making any shoe design. The last is what makes a shoe suitable for playing basketball, climbing mountains, or strutting down the runway.
When discussing the many attributes of a last you will need to know the common terms. The majority of footwear last measurements are measured by volume around the last, rather than the traditional length and width associated with shoe fit. A flexible measuring tape is a key tool for checking lasts.
Parts of a Last – Shoe Last Diagram
The parts of the last include the forepart, instep, cone, back part, waist, and seat. If the last is hinged it will have a vent above the hinge point. A hinge is needed to prevent damaging a shoe when it is being removed from the last. Shoe lasts may have tiny bumps marking the vamp point, toppling point, and counterpoints. The last terms are the same for men’s sports shoes or women’s fashion shoes.

Heavy paper templates or last gauges are cut by computers. The gauges are marked with critical dimensions, the last size, and code number. The paper gauges are used to check every size of the sample lasts. Once the last fitting has been confirmed, the same paper gauges are used to confirm the production lasts.
