Embodiment Construction

[0021] Referring to FIG. 1, the present invention includes generally a shoe 10 having an outsole 12, a midsole 14, and an insole 16. In the preferred embodiment of the present invention, shoe 10 is any shoe including but not limited to an athletic shoe, a casual shoe, a boot, a sandal, a dress shoe, etc.

[0022] Outsole 12 of shoe 10 is commonly made from a variety of materials including elastomer styrene-butadiene rubber or a carbon fiber rubber. Lying on the bottom side of shoe 10, outsole 12's main purpose is to provide friction and durability. Different treads on outsoles 12 define shoe 10's purpose. For example, on an athletic shoe, waffle-studded treads act like support columns to absorb and dissipate impact.

[0023] Just above outsole 12 is midsole 14. Midsole 14 absorbs impact by cushioning but also returns energy to the person wearing shoe 10 (e.g., a runner). The most common material used in the manufacturing of midsoles is a plastic foam consisting of ethylene, vinyl, and a...

In particular, the present invention relates to a shoe with a sole that is filled with a loose fill material such as crumb rubber for shock absorption, cushionability, energy return, added comfort and stability. [0003] 2. Discussion of the Related Art [0004] Dress, casual and athletic shoes generally include an upper leather portion and an inner lining that cover the top of the foot, a counter placed between the upper leather portion and the lining to provide rigidity at the heel, an insole upon which the foot rests, an outsole which contacts the ground surface and possibly a filler portion that is positioned between the insole and outsole. The midsole of a shoe is a piece of material such as rubber or leather that is often stitched or glued to the inside fabric lining, upper leather portion, and the counter to hold the constru...
