Embodiment Construction

[0026]Referring now to the drawings. FIG. 1 shows one of the inserts 10, including midsoles, footbeds, sockliners and / or upper components 10 from the top. As seen in FIGS. 2 and 3, the insert 10, which is transparent, including midsoles, footbeds, sockliners and / or upper components is composed of a thin outer membrane 15 that is typically made from a flexible material, such as thermal polyurethane or elastomeric silicone.

[0027]The side views shown in FIGS. 2 and 3, along with the cross-sectional view shown in FIG. 3A demonstrates how the granular particles 20 are positioned inside the outer membrane 15.

[0028]FIG. 2 shows one interior compartment 16a wherein granular ethyl vinyl acetate 20 is injected into the interior compartment 16a. FIG. 3 demonstrates how a second interior compartment 16b can be utilized to prepare the inserts 10, including midsoles, footbeds, sockliners and / or upper components with more than one interior compartment for the desired comfort level and density of t...

Abstract

Shoe inserts, including midsoles, footbeds, sockliners and/or upper components with a moldable outer membrane having an upper portion and a bottom portion, with the bottom portion being injected through an injection means with one or more layers of granular ethyl vinyl acetate through one or more compartments located inside of the outer membrane, the layers of granular ethyl vinyl acetate being of various densities to fit the particular application, the granular ethyl vinyl acetate being produced through the breaking down of the physical state of solid foam ethyl vinyl acetate and with the granular ethyl vinyl acetate optionally containing on or more variety of colors.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to the field of shoe inserts, including midsoles, footbeds and / or upper components, designed for comfort, ranging from the casual shoe to the athletic shoe and a method for manufacturing same.[0003]2. Description of the Prior Art[0004]Shoe inserts, including midsoles, sockliners, footbeds and upper components, are well-known in the art as articles added to shoes both for comfort and improved athletic performance, among other things. Many people do not have proper alignment in their feet for the proper gait needed for optimal alignment and health. For these people, modifications to their footwear are needed. A common modification for this purpose is the addition of inserts, including midsoles, footbeds, sockliners and / or upper components of one type or another, including those that can correct misalignment and improve, comfort, walking and athletic performance.[0005]Shoe inserts, i...
