The present application teaches a device and method for adjusting the width, girth, and foot shape of an article of footwear. Lasting boards having different configurations and alternate positions for selectively affixing various portions of an upper can be used to adjust and customize the fit of an article of footwear for an individual wearer. The lasting board can also comprise a spring element which can provide improved cushioning, stability, running economy, and a long service life. Unlike the conventional foam materials presently being used by the footwear industry, the spring element is not substantially subject to compression set degradation and can provide a relatively long service life. The components of the article of footwear including the upper, insole, lasting board and/or spring element, and sole including possible midsole and outsole portions 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, midfoot and rearfoot areas of the article of footwear can be readily modified and adjusted. Accordingly, the article of footwear can be customized by a wearer or specially configured for a select target population in order to optimize desired performance criteria. Moreover, the present invention teaches a novel method of manufacturing an article of footwear, and also, a novel way of doing both retail and Internet business.
