Abstract

Abstract A personalized insert (20) containing a resilient material (41) is employed within an article of footwear (44) in order to enhance conformance, control, stability, support and comfort. The resilient material (41) is contained within a casing (22) of suitable configurations. Removal of restraining pin(s) (24), and/or the rupture of membrane(s) (62) isolating the reagents (27) then permits fluid communication and proper mixing of the resilient material (41). The resilient material (41) then sets in conformance with the wearer's foot (28) when the insert (20) is secured within an article of footwear (44). The invention permits accommodation to the wide range of foot (28) and arch )34) characteristics found amongst the general public and application within numerous types of footwear.
