Embodiment Construction

[0029] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0030] figure 1 A shoe sole is shown, the heel portion 16 of which employs a preferred embodiment of the liner 10 of the present invention. The sole includes a midsole 12 and an outsole 14 . In this embodiment, the liner 10 is an integral part of the midsole 12, but its underside is partially exposed for contact with the ground and thus also serves as an outsole.

[0031] refer to figure 2 , the pad has an outer tubular portion 24 comprising an inner tubular portion 18 and an outer tubular portion 20 formed by elastic load-bearing tubular walls 19 . Tubular portions 18 and 20 extend along the medial and lateral sides of the sole's foot shape. In a preferred embodiment, tubular portions 18 and 20 extend along the medial and lateral sides of the heel shape of the foot, generally in the heel region of the sole, facing each other toward central portion 26 . While tubular portions 18 and 20 also extend along the heel-s...

Abstract

A shoe sole for supporting a wearer's foot. The sole has a main sole portion and at least one cushion (10) associated with the main sole portion. The cushion (10) includes first and second hollow tubular portions (18 and 20), preferably with resilient load bearing first and second hollow walls that have a thickness, material, and shape providing sufficient strength for supporting and cushioining the sides of a corresponding foot region of a wearer's foot. The first wall is disposed on first side of a sole region of the sole, and the second wall is disposed on a second side of the sole region opposite from the first side. At least one of the first and second hollow walls extends along a third side of the sole region. A central portion (26) of the cushion (10) is disposed between and joined with the first and second tubular portions (18 and 20), and preferably has a thickness, material, and shape providing sufficient strength for supporting and cushioning a generally central part of the foot region between the first, second, and third sides.

Description

[0001] This application is a continuation-in-part of Application Serial No. 08 / 985999, filed December 5,1997. field of invention [0002] The present invention relates to a liner placed in the sole of a shoe to cushion and support the foot. More specifically, the present invention relates to a pad having a U-shaped tubular portion disposed around a central portion of the supporting foot region. Background of the invention [0003] Resilient athletic shoe soles are constructed of various resilient cushioning elements which are used to store and absorb impact energy imposed on the wearer's foot. Many well-known shoe soles include fluid bladders, which contain compressed air, or viscous liquids or gels to absorb impact and store energy. [0004] For example U.S. Patent No. 5,406,719 discloses a bladder in which air is compressed. The bladder includes a heel rest with various air chambers. Some air chambers are placed around the perimeter of the heel cup, while others are loc...
