What Is A Shoe Last? Valisa R. October 23, 2017 16:46 Updated A shoe last is a 3-dimensional wooden or plastic mold upon which a shoe is constructed. The last used during shoe assembly can affect the overall fit of a shoe, and all lasts include the following dimensions: heel width, instep height, forefoot width, and toe box depth. Some of our shoes feature a deeper toe box or a wider forefoot, while others might offer a narrower heel. We manufacture shoes using a variety of lasts and offer extensive width sizing to allow for the best overall fit in the shoe industry. We aim for a 360° fit, while most other companies simply try to fit your length. The vast majority of shoe fit issues can be resolved by changing either the size or width (or both), and the last upon which a shoe is built could also affect fit. If you are able to go into any shoe store and purchase a shoe right off the shelf, we suggest choosing a standard width (B for women and D for men). If wider or narrower widths suit you better, we certainly have many options for you. To discuss different fit types, please reach out to us via phone or email.
