ABSTRACT:
A midsole construction or insert 20 comprising a two-part composition 41 and entrapped air cushion 40 is employed within an article of footwear 44 in order to enhance conformance, stability and comfort. Said composition 41 and entrapped air 40 are contained within a bi-pac of suitable configurations. The removal of a restraining pin 24 permits the reagents to mix freely and set in conformance with the wearer's foot 28 after insertion into an article of footwear 44. The midsole construction or insert 20 is configured to underlie the area of the heel 30 and extend to just short of the metatarsal heads 32, thus achieving conformance and stabilizing the heel 30 and arch(es) of the foot 28. The entrapped air 40 is configured to underlie the apex of the arch(es) 34 so as to accomodate their dynamic movement.
