Description
    TECHNICAL FIELD
  • [0001]
    This invention relates generally to a shoe sole structure for footwear. More particularly, the present invention relates to a shoe sole structure that not only provides a shock absorbing effect but also can protect the elastic portion of the shoe sole structure from aging and wear.
  • BACKGROUND OF THE INVENTION
  • [0002]
    Shoes, especially for jogging, running or other sport purposes, have two basic requirements. The principal task of the shoe is to help the act of running, so that the runner moves forwardly as sparingly as possible. The other task of the shoe is to protect the feet for running exertion, so that conditions for the runner's optimum performance may also be preserved or maintained through the latter part of a running race. In addition, in a consumer's point of view, longer life of a shoe sole structure is preferred. To achieve the aforementioned functions, many different shoes have been developed
  • [0003]
    Resilience of the sole can be obtained in many different ways. For example, a traditional shoe sole structure is composed of a foaming material for providing elasticity and a rubber layer combined with the foaming material for protecting the foaming material. However the rubber layer can only protect the bottom portion of the foaming material. The surroundings of the foaming are not protected. Therefore the foaming material exposes to sunlight and moisture directly. That causes the foaming material aged and worn quickly. Besides, for the purpose of running or other sports with heavy duties, the elasticity provided by the foaming material of the traditional shoe sole structure is not enough.
  • [0004]
    Another design of traditional shoe sole structure is an air cushion structure. However, the cost of air cushion shoe sole is high and the procedure of manufacturing is complex. In addition, sometimes unnecessary deformations take place in the shoe sole of air cushion structure. Accordingly a shoe sole structure with sufficient and proper elasticity as well as long life and comparatively low cost of manufacture is needed.
  • SUMMARY OF INVENTION
  • [0005]
    It is therefore an objective of the present invention to provide a shoe sole structure with sufficient and proper elasticity.
  • [0006]
    A further important object of the present invention is to provide a shoe sole structure that can prevent the elastic portion of the sole from aging and wear.
  • [0007]
    The present invention, briefly summarized, in one embodiment discloses a shoe sole structure. The shoe sole structure contains a first protective container, a first elastic pad, a second protective container and a second protective container. The first protective container has a first side having a first containing space and a second side having plural first gutters thereon. The first elastic pad is united with the first side within the first containing space. The second protective container has a third side having a second containing space and a forth side having plural second gutters thereon. The second elastic pad is united with the third side within the second containing space. The second side is united with the forth side. Another embodiment of the present invention discloses a shoe sole stricture containing a protective container, an elastic pad and an outsole. The protective container has a first side having a containing space and a second side having plural gutters thereon. The elastic pad is united with the first side within the containing space. The outsole is united with the second side of the protective container.
