Abstract
Articles of footwear have a sole structure that extends along the longitudinal length of the article of footwear within the forefoot region, the midfoot region, and the heel region of the article of footwear. One or more removable inserts may be inserted into at least a portion of the sole structure in any desired region. Various removable inserts may have different characteristics, including different performance characteristics. The various removable inserts may be inserted into and removed from the sole structure of the article of footwear. A wearer may be able to compare the characteristics for each of the removable inserts. Such a process may help a wearer to determine the more favorable characteristics for an article of footwear; may facilitate testing of sole structures or other components of an article of footwear for a manufacturer or developer of articles of footwear; may help train wearers who test the articles of footwear for such a manufacturer or developer; may improve versatility of a single article of footwear; and the like.
