Methods and systems for customizing wearable equipment such as athletic equipment, including ice skates. For example, an ice skate may comprise a skate boot and blade holder. The skate boot may be customized, e.g., may be manufactured using a custom last. A method of operating a computing device to customize the skate boot last may comprise: carrying out a 3D modeling application; obtaining a scan of a foot from an image acquisition device; creating a model of the foot; obtaining a model of a customized last based on the model of the foot; creating metadata and associating the metadata with the 3D model data; and generating a production specification for the customized last based on the model of the customized last and the metadata.
