ABSTRACT:
A layered cushioning system for a shoe sole for women's pumps is characterized by a flexible polyurethane outsole containing a recess in the upper forepart thereof within which is molded a shock-absorbing foam insert. A rigid insole tuck having a steel shank and a contoured configuration is mounted on the outsole and extends from the heel to the arch. A shock-absorbing heel pad is connected with the upper surface of the tuck in the heel area. Mounted on the insole tuck is a socklining including a lower shock-absorbing foam layer and a urethane coated cover. A further shock absorbing foam insole is provided for the forepart area. The sole thus has superior cushioning, flexibility in the forepart region and stability in the rear.
