Problems solved by technology

When the runner is heavy, the heel cushioning material may “bottom out” before heel impact is completely absorbed, which can results in shock-related injuries.
On the other hand, if the cushioning material is too soft, poor lateral foot stability may result in injuries.

Embodiment Construction

[0042]Referring to FIGS. 2 and 5, a fabrication method of an air cushion assembly according to one embodiment of the present invention includes the steps of inserting a melting inflatable bladder 40 or tube (not shown) together with a cushioning element 22 in a blowing mold 3 having an upper side, and an opposite, lower side, an exterior surface and an interior surface, inflating the melting inflatable bladder 40 with air in high pressure, so as to form a bladder 41 with a passage way 42 conforming to the inner shape of the blowing mold 3, and blowing air into the bladder 41 in a first inner pressure; and thereafter sealing the passage way 42 for forming a first air cushion 4 which connects the cushioning element 22 on one side. The resulting air cushion with multistage shock-absorbing assembly includes a stacked structure of the upper side of the blowing mold 3, the melting inflatable bladder 40, the cushioning element 22, and the lower side of the blowing mold 3 as shown in FIG. 2...

Abstract

An air cushion connected at least a cushioning element in a vertical stack configuration for absorbing both lighter and heaver heel impacts sequentially in a shoe mid-sole. The air cushion includes a first air bladder and a cushioning element forming a vertical stack configuration such that when the impact lighter than a predetermined value is applied to the vertical stack configuration, it is absorbed by deforming the first air bladder only, and when the impact heavier than the predetermined value is applied to the vertical stack configuration, it is absorbed by deforming both the first air bladder and the cushioning element.
