The present application teaches a device and method for adjusting the width, girth, and foot shape of an article of footwear (22). Lasting boards (79) having different configurations and alternate positions for selectively affixing various portions of an upper (23) can be used to adjust and customize the fit of an article of footwear (22) for an individual wearer. The lasting board (79) can also comprise a spring element (51) which can provide improved cushioning, stability, running economy, and a long service life. Unlike the conventional use of foam materials presently, the spring element (51) is not substantially subject to compression set degradation and instead can provide a relatively long service life. The components of the article of footwear (22) can be selected from a range of options, and can be easily removed and replaced, as desired. Further, the relative configuration and functional relationship as between the forefoot (58), midfoot (67) and rearfoot (68) areas of article footwear (22) can be readily modified and adjusted. Accordingly, the article of footwear (22) can be customized for a select target population to optimize desired performance criteria. The present invention teaches a novel method of manufacturing an article of footwear (22), and also, a novel way of doing both retail and Internet business. |
