The present invention teaches a method of conducting retail and Internet
business including making and delivering a custom article of footwear.
The article of footwear taught in the present invention includes a spring
element that can provide improved cushioning, stability, and running
economy. Unlike the conventional foam materials presently being used by
the footwear industry, a preferred 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, heel counter, spring element, and sole can be selected
from a range of options, and can be easily removed and replaced, as
desired. Accordingly, the present invention also teaches a method of
making a custom article of footwear.
