Embodiment Construction

[0033] Referring now to the drawings, and in particular to Figures 1 to 9, there will be described a shoe generally indicated at 10 according to a preferred embodiment of the present invention.

[0034] The present invention uses multiple pre-molded hollow tubes whose function is to vary the amount of shock absorption of the shoe. The tubes, which are circular or oval in cross-section, are preferably made of elastic plastic or elastomeric material and act as bows or springs to absorb impact forces. The amount of damping required depends on the material, geometry, location and orientation of each tube.

[0035] The material used for the tubes can alter the resulting shock absorption. For example, if a high degree of shock absorption is required, the material should be an elastomeric grade material with a Shore A hardness of 30-50, such as thermoplastic polyurethane (TPU), or thermoplastic Rubber (TPR), or thermoplastic elastomer (TPE). An example is the GLS Dynaflex. If les...

Abstract

A midsole for footwear includes at least one solid or hollow cushioning tube positioned therein for improving the cushioning of the midsole. Preferably, the midsole includes a plurality of cushioning tubes fabricated of an elastomeric material. The tubes may vary in diameter and / or wall thickness relative to one_another for varying the cushioning and stability characteristics of the system. Each tube may also vary in diameter and / or wall thickness along its length.

Description

technical field [0001] The present invention relates to a shock absorbing device for the midsole of an athletic shoe, and in particular the design of the device can be changed to provide different amounts of shock absorbing at different locations along the midsole of the shoe. [0002] The present invention relates to an improved shock absorbing system for footwear. In particular, the system is made of tubular inserts located in the midsole, for example in the forefoot or heel area. These tubular inserts provide the difference in shock absorption and stabilization of the midsole, and can be altered to provide specific shock absorption, or to provide better stability in specific locations if desired. [0003] The stability of the athletic shoe is very important in preventing the rolling of the foot known as pronation or supination. Shock absorbing devices should not compromise the stability of the shoe. Stability is not sacrificed and shock absorption is enhanced using the d...
