Article of footwear with a removable foot-supporting insert
An article of footwear is disclosed that includes an upper that defines an interior void, a sole structure secured to the upper, and a foot-supporting insert that is positionable within a lower area of the void and removable from the void. A system having a protrusion and an indentation may be utilized to, for example, secure the insert within the void. As an example, a protrusion may extend outward from a surface of the void, and the insert may define an indentation in a corresponding location and with a corresponding shape. When the insert is positioned within the void, the protrusion will extend into the indentation. The locations, shapes, numbers and overall configuration of the protrusion and indentation may vary significantly.
1. A method for manufacturing an article of footwear, the method comprising steps of:
forming an upper with a void having dimensions corresponding with a combination of a foot and a foot-supporting insert;
removing the foot-supporting insert and customizing the foot-supporting insert to a shape specific to a wearer;
affixing a label to at least one of the footwear and a container for the footwear indicating the footwear is designed for a particular athletic activity; forming a first portion of a securing system on a lower surface of the void in the upper and forming a corresponding second portion of the securing system in a surface of the foot-supporting insert; and
wherein the forming the first portion and second portion of the securing system includes forming a tapered protrusion and a tapered indentation, with corresponding shapes, the lower surface of the void defining one of the tapered protrusion and the tapered indentation in a location that is spaced inward from side surfaces of the upper, and a lower surface of the insert defining the other of the tapered protrusion and the tapered indention, the tapered protrusion being positioned to receive the tapered indentation when the insert is positioned within the void and the lower surface of the insert contacts the lower surface of the void.
2. The method of claim 1 , wherein the step of forming the upper and the void having dimensions corresponding with a combination of a foot and foot-supporting insert includes forming the upper and the void having additional depth.
3. The method of claim 1 , further including forming at least one protrusion and at least one recess in the footwear and the foot-supporting insert.
4. The method of claim 3 , wherein the at least one protrusion and the at least one recess have a shape that corresponds to each other.
5. The method of claim 1 , wherein the foot-supporting insert is uniquely configured to fit the footwear.
6. The method of claim 1 , wherein customizing the foot-supporting insert includes forming an upper surface of the foot-supporting insert to a shape that benefits the wearer.
7. The method of claim 1 , wherein customizing the foot-supporting insert includes molding the foot-supporting insert to have specified contours, the contours being specified by a person other than the wearer.
