ABSTRACT:
A sneaker or canvas shoe having an insole comprising a soft pad which is encased in a sealed film envelope to prevent the pad from absorbing moisture, odors and contamination. The envelope includes a chamber disposed beyond an end of the pad into which air can be forced, from the area of the envelope surrounding the pad, when pressure is applied to the insole by the weight of the wearer of the shoe. A part of the air chamber is heat sealed to the toe portion of the shoe, during the manufacture of the shoe, to retain the insole correctly positioned within the shoe.
