Claim 11

A sole as claimed in claim 2 which is manufactured from rubber and each layer is vulcanized to the immediately adjacent layers.

Claim 12

A sole for use in a shoe as claimed in claim 1 wherein said mid-sole includes a plurality of semi-circular depressions on its upper surface and said air-chamber member includes a plurality of identical and complementary semi-circular depressions on its lower surface, said plurality of depressions forming said plurality of discrete, vertically-aligned sealed air-chambers when said mid-sole and said air-chamber are sealed together.

Claim 13

A sole for use in a shoe as claimed in claim 1 wherein said air-chamber member further includes a plurality of alveoli depending downwardly from its lower surface, each of the alveoli of the air-chamber member off-set with a corresponding alveoli of the mid-sole and adapted to form a continuous series of alternate discrete sealed air-chambers when said mid-sole and said air-chamber member are sealed together.

Claim 14

A one-piece sole for use in an athletic shoe which comprises: (a) a base member carrying on its underneath surface, a plurality of ground gripping studs; (b) a thin, lower sealing member; (c) a mid-sole containing a plurality of discrete, vertically-aligned alveoli extending from the top surface of said mid-sole downwardly to a point marginally above the bottom surface of said mid-sole, the height of the said mid-sole greater at the heel portion than at the toe portion; and the concentration of said alveoli greater in the portion of the mid-sole corresponding to the ball and plant of the foot and the lateral side of said mid-sole; (d) an air-chamber member comprising a thin, resilient member with a plurality of downwardly depending, open-topped discrete air-chambers, said air-chambers corresponding in size, shape and position to said alveoli in said mid-sole; (e) an upper sealing member adjusted to overlay said air-chamber member and to seal said air-chambers.

Claim 15

A one-piece sole for use in an athletic shoe which comprises: (a) a base member carrying on its underneath surface, a plurality of ground gripping studs; (b) a thin, lower sealing member; (c) a mid-sole containing a plurality of discrete, vertically-aligned alveoli extending from the top surface of said mid-sole downwardly to a point marginally above the bottom surface of said mid-sole, the height of the said mid-sole greater at the heel portion than at the toe portion; and the concentration of said alveoli greater in the portion of the mid-sole corresponding to the ball and plant of the foot and the lateral side of said mid-sole; (d) an air-chamber member comprising a thin, resilient member with a plurality of downwardly depending, open-topped discrete air-chambers, said air-chambers corresponding in size, shape and position to said alveoli in said mid-sole; (e) an upper sealing member adjusted to overlay said air-chamber member and to seal said air-chambers.

Claim 16

In a shoe comprising an upper portion and a sole portion, the improvement comprising the sole consisting of a one-piece sole for use in an athletic shoe which comprises: (a) a base member carrying on its underneath surface, a plurality of ground gripping studs; (b) a thin, lower sealing member; (c) a mid-sole containing a plurality of discrete, vertically-aligned alveoli extending from the top surface of said mid-sole downwardly to a point marginally above the bottom surface of said mid-sole, the height of said mid-sole greater at the heel portion than at the toe portion; and the concentration of said alveoli greater in the portion of the mid-sole corresponding to the ball and plant of the foot and the lateral side of said mid-sole; (d) an air-chamber member comprising a thin, resilient member with a plurality of downwardly depending, open-topped discrete air-chambers, said air-chambers corresponding in size, shape and position to said alveoli in said mid-sole; (e) an upper sealing member adjusted to overlay said air-chamber member and to seal said air-chambers; and a wedge inserted in said shoe on the top of said upper sealing member of said sole, said wedge consisting of a wedge-shaped arch support for use in a shoe which comprises a raised area corresponding to the heel of the foot, the lateral portion of the wedge decreasing in height from the heel to the toe and the medial portion sloping marginally from the heel forward to the ball portion of the foot then convexly downward to the toe.

Claim 17

In a shoe comprising an upper portion and a sole portion, the improvement comprising the sole consisting of a one-piece sole for use in an athletic shoe which comprises: (a) a base member carrying on its underneath surface, a plurality of ground gripping studs; (b) a thin, lower sealing member; (c) a mid-sole containing a plurality of discrete, vertically-aligned alveoli extending from the top surface of said mid-sole downwardly to a point marginally above the bottom surface of said mid-sole, the height of said mid-sole greater at the heel portion than at the toe portion; and the concentration of said alveoli greater in the portion of the mid-sole corresponding to the ball and plant of the foot and the lateral side of said mid-sole; (d) an air-chamber member comprising a thin, resilient member with a plurality of downwardly depending, open-topped discrete air-chambers, said air-chambers corresponding in size, shape and position to said alveoli in said mid-sole; (e) an upper sealing member adjusted to overlay said air-chamber member and to seal said air-chambers; and a wedge inserted in said shoe on the top of said upper sealing member of said sole, said wedge consisting of a wedge-shaped arch support for use in a shoe which comprises a raised area corresponding to the heel of the foot, the lateral portion of the wedge decreasing in height from the heel to the toe and the medial portion sloping marginally from the heel forward to the ball portion of the foot then convexly downward to the toe.
