CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of U.S. Provisional Patent Application No. 62/241,346, filed on Oct. 15, 2015, entitled “Running Shoe Outsole”, the entire invention of which is incorporated by reference herein.

FIELD OF THE INVENTION

The present invention is a running shoe outsole. More specifically, the present invention relates to running shoe outsoles for track and field.

BACKGROUND

Every shoe has a sole. A sole is the part of a shoe which the foot rests and which makes contact with the ground. Soles can be simple with a single material in a single layer. Or soles can be complex with multiple structures, layers, and materials. When soles contain multiple layers, soles generally consist of three layers including an insole, a midsole, and an outsole.

The insole is the interior bottom of a shoe, which sits beneath the foot under the footbed or the sock liner. The midsole is the layer between the insole and the outsole and is generally used for shock absorption. Midsoles are typically made of plastic materials that feel and behave like foam or rubber. Midsoles provide cushioning and stability in the shoe.

The outsole of a shoe is the layer in direct contact with the ground. An outsole may comprise a single piece of material or an assembly of separate pieces, often comprising different materials. Outsoles are important because they provide the wearer with grip, support, and cushioning while the wearer is walking, jogging, or running. Shoe outsole materials and designs vary depending on the type of activity for which they are intended.

Dress shoe outsoles are made of leather and are generally designed for aesthetic appeal rather than function and comfort. Casual shoe outsoles are generally made of soft rubber and are designed for comfort and stability. Hiking shoe outsoles are typically deep-lugged soles of tough rubber to provide friction to avoid slipping on any surface. Hiking shoe outsoles absorb and re-direct shock, providing support and cushion for the wearer.

Athletic shoe outsoles, including running shoe outsoles, are generally made from carbon rubber or blown rubber. Carbon rubber is a hard type of rubber while blown rubber is a soft type of rubber. Running shoes are a type of athletic shoe and are generally divided into cross country running shoes and track and field shoes. Cross country running shoe outsoles are generally made from carbon rubber and are designed to provide traction, support, cushioning, flexibility, and durability for long distance running.

Track and field shoe outsoles generally consist of elastic materials such as polyamide, polyurethane, or polyethylene. Track and field shoe outsoles are designed to be as lightweight and flexible as possible, while providing shock absorption, tensile strength, and cushioning.

The general structure of a track and field sprinting shoe outsole includes a toe region, further extending to a ball region, further extending to an instep region, further extending to an arch region, further extending to a heel region.

Nearly all track and field shoe outsoles designed for sprinting have a hard plate at the toe and ball regions of the foot, known as the forefoot region. Such hard plates at the forefoot region contain spike wells, allowing spikes and cleats to protrude from the bottom surface of the outsole, thereby increasing grip on the track surface.

Track shoe outsoles designed for sprinting are very flexible in order to maximize their performance, particularly at the starting blocks.

In light of the current state of the track and field running shoe art, there is a current and unmet need for a sprinting shoe that provides increased shock absorption and support to the runner while maintaining essential lightweight, flexibility, and durability characteristics. Such cushioning and support reduces stress on the feet and joints of a runner over time, thereby protecting the runner from injury resulting from constant impact against the ground.

SUMMARY OF THE INVENTION

The present invention, in its many embodiments, relates to a running shoe outsole made from two layers of strong yet flexible material providing enhanced shock absorption and support for a runner's foot as it impacts the ground while running. The present invention describes a running shoe outsole that increases shock absorption and support to the runner while maintaining essential lightweight, flexibility, and durability characteristics. Such cushioning and support reduces stress on the feet and joints of a runner over time, thereby protecting the runner from injury resulting from constant impact against the ground. This protection allows the runner's sponsors, including, but not limited to, venues, to capitalize on the runner's prolonged athletic career and increase the overall profits brought in by the runner. Therefore, the present invention enables a sprinter to have a prolonged running life, free from impact-related injuries.

In one embodiment, the present invention relates to a running shoe outsole, which is designed primarily for track and field sprint events and training.
