Performance-enhancing footwear that augments human biomechanics of the leg, ankle, and foot
An article of footwear to improve walking ease and comfort, increase running speed, and improve jumping ability by augmenting the natural musculature and biomechanical characteristics of the lower leg, ankle, and foot portion of the human body. Walking, running, and jumping involves a complex series of joint and muscle movements. One of the critical components of this motion is the exertion of muscle force and/or tendon stress at the lower leg, ankle, and foot when releasing weight from the back foot during walking or running (the push off), or from one or both feet when jumping. The present invention augments this natural process by allowing storage of energy within energy storage and release means (35) as the angle θ produced by the intersection of the lower leg axis and foot axis is decreased (the forward portion of the foot moves closer to the shin) when a person moves forward during walking or running, or when a person jumps. The energy stored within the energy storage and release means (35) is released as the person continues with forward and/or upward motion, augmenting the natural musculature, allowing longer and/or easier steps, and/or higher jumps. The energy storage and release means (35) of the present invention connect, or are secured by mounting means that connect, portions of the footwear above the level of the ankle joint and portions of the footwear below the level of the ankle joint, thus taking advantage of the change in θ that occurs during walking, running, or jumping. Because the present invention utilizes the natural motion, musculature, and biomechanics of normal walking, running, or jumping, it provides a more stable, comfortable, and efficient method to achieve the desired goal of walking more easily, running faster, or jumping higher.
1. Field of Invention
This invention relates to performance-enhancing footwear, more specifically, footwear that incorporate at least one energy storage and release means.
2. Description of Prior Art
The present invention is a unique article of footwear that incorporates at least one energy storage and release means which may be advantageously used in a preferred embodiment of the invention to enable the wearer of said article of footwear to walk easier, run faster, or jump higher than without said article of footwear. Force generated as a wearer's angle joint is compressed (foot-leg angle decreases) is stored in an energy storage and release means and is later released at an advantageous time.
The prior art includes a large number of footwear devices that include energy storage and release means. However, all of the prior art devices appear to place the energy storage and release means in the toe, base, or heel portion of the footwear. The position and function of the energy storage and release means of the prior art results in instability and minimal improvements to the natural walking, running, and jumping ability of a wearer. These prior art devices do not take sufficient advantage of the natural motion, musculature, and biomechanics associated with normal walking, running, and jumping.
Accordingly, an article of footwear which improves the natural walking, running, and jumping ability of humans by taking advantage of the natural function and process associated with the bending and straightening of the lower leg-foot angle when walking, running, or jumping, is highly desirable.
OBJECTS AND ADVANTAGESAccordingly, besides the objects and advantages of the article of footwear described in my patent, several objects and advantages of the present invention are:
-
- (a) to provide an article of footwear that utilizes at least one energy storage and release means to augment the natural musculature of the human body;
1(b) to provide an article of footwear that takes advantage of the natural biomechanics of the human body involved with walking;
-
- (c) to provide an article of footwear that takes advantage of the natural biomechanics of the human body involved with running;
- (d) to provide an article of footwear that takes advantage of the natural biomechanics of the human body involved with jumping;
- (e) to provide an article of footwear that allows easier walking;
- (f) to provide an article of footwear that allows faster running;
- (g) to provide an article of footwear that allows higher jumping;
- (h) to provide an article of footwear that utilizes energy storage and release means, without causing significant instability to the user, by mimicking the natural musculature and biomechanics of the human body involved with walking, running, or jumping.
Further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

Operation—
The present invention represents a radical change from the prior art in regards to utilization of energy storage and release means as part of footwear designs. Embodiments associated with this invention utilize one or more energy storage and release means that link a portion of the footwear above the level of the ankle joint with a portion of the footwear below the level of the ankle joint (
The present invention augments the natural musculature and biomechanics associated with walking, running, or jumping by providing one or more energy storage and release means that function in a similar manner to the natural human musculature and biomechanics. Through incorporation of one or more energy storage and release means at the frontal, top portion of the footwear (

In embodiments of the present invention that utilize one or more energy storage and release means located in some combination of front, side, and rear positions of the footwear, connection is made between portions of the footwear above the ankle joint and portions of the footwear below the ankle joint such that energy is stored in the energy storage and release means when θ decreases, and energy is released from the energy storage and release means when θ increases.
Summary, Ramifications, and Scope
Accordingly, the reader will see that the present invention provides innovative augmentation of the natural musculature and biomechanics of the human foot such that walking takes less effort, running can be done more quickly, and heights of jumping can be increased. Additionally, embodiments of the present invention provide more stable augmentation than previously attempted through the prior art.
Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example, rather than three, top-mounted energy storage and release means, two, or more than three, could be used. Any combination of energy storage and release means located anywhere on the footwear, such that the means, or attachment means used to secure the energy storage and release means, provide a link between a portion of the footwear above the level of the ankle, and a portion of the footwear below the level of the ankle, and utilizing the changing angle θ, formed by the intersection of the foot axis and lower leg axis, such that energy is stored in energy storage and release means when θ decreases, and energy is released from energy storage and release means when θ increases, would conceptually be included within the scope of this invention, even though not necessarily illustrated in one of the included figures.
Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
