Abstract
A method of lasting an upper for an article of footwear can include inserting a last in a collapsed state into an upper. The last can include at least two parts movable relative to each other so as to allow the last to be collapsed along a substantially longitudinal direction from an extended state to the collapsed state. The last can also include at least one fastener configured for attaching string and configured to hold string in the collapsed state and in the extended state of the last. The method can further include attaching the upper to the fastener using at least one string and extending the last. For example, the act of extending the last may increase tension in the string in a manner that draws the upper about the last.
