Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
Embodiments of the present invention generally relate to footwear, and more particularly to footwear soles and the usefulness of footwear sole in cleated athletic shoes prevalent in sports such as soccer, football, baseball or the like, enhancing athletes performance and balance while preventing injury.
2. Description of the Related Art
Athletic shoes with cleats provide traction, without taking into account the biomechanics and biometrics of an athlete. The modern athletic shoe is a highly refined combination of elements which cooperatively interact in an effort to minimize weight while maximizing comfort, cushioning, stability and durability. However, these goals are potentially in conflict with each other in that the efforts to achieve one of the objectives can have a deleterious effect on one or more of the others. Moreover, the deleterious effect is prominent in a high performance cleated shoes. As a result, the shoe industry continues in its efforts to optimize the competing qualities of cushioning, durability and stability.
In athletic shoes the sole ordinarily has a multi-layer construction comprised of an outsole, a midsole and an insole. The outsole is normally formed of a durable material to resist wearing of the sole during use. In many cases, the outsole includes lugs, cleats or other elements to enhance the traction afforded by the shoe. The midsole forms the middle layer of the sole and is typically composed of a soft foam material to cushion the impact forces and pressure experienced by the foot during athletic activities. The foam midsole may be formed with or without the inclusion of other cushioning elements, such as a resilient inflated bladder. An insole layer is usually a thin padded member provided overtop of the midsole to enhance the comfort afforded to the wearer.
Athletic shoes by and large are deficient in providing proper balance and safety for the wearer. Consequently, numerous injuries are sustained by those engaging in athletic activities. To overcome these shortcomings, over the years manufacturers focused their attention upon enhancing only the spikes of the athletic shoes. To this end, over time outsoles have been modified to provide better traction. These endeavors have further led to the incorporation of other cushioning elements within the midsoles (e. g., resilient inflated bladders) and other sole configurations intended to provide enhanced cushioning effects. The industry's focus on improving traction has resulted in a marked improvement of shoes in this regard. However, footwear stability has not always been so successfully addressed. In fact, the benefits realized in traction and cushioning have sometimes led to a degradation of the shoe's stability.
To appreciate the potential harmful effects that could be attributed to instability, it is important to have a basic understanding of the dynamics of running. While the general population includes a wide variety of running styles, most people run in a heel-to-toe manner. However, in this running style the foot does not normally engage the ground in a simple back to front linear motion. When a person runs, the feet generally engage the ground under the approximate midline of their body, rather than to the sides as in walking. As a result, the foot is tilted upon ground contact such that initial engagement with the ground (commonly referred to as the “rear foot strike”) usually occurs on the lateral rear corner of the heel.
At rear foot strike, then, the foot is ordinarily oriented with the big toe pointing upward and slightly outward. As the ground support phase progresses the foot is lowered to the ground in a rotative motion such that the sole comes to be placed squarely against the ground. Inward rotation of the foot is known as eversion and, in particular, inward rotation of the calcaneus associated with articulation of the subtalar joint is known as rear foot pronation. While, eversion is itself a natural action, excessive pronation, or an excessive rearward rate of pronation is sometimes associated with injuries among runners and other athletes.
Additionally, cleats are provided on the outsole to help with traction. The major drawback with the cleats is that the athletes draw more energy to run as they dig the foot out of the dirt or mud or ground. The cleats when dug into the ground causes delay in reaction time for athlete.
Additionally, the cleats are cause of injuries to athletes as the cleats twists the athlete's feet's. As an athlete is engaged in the sports the athlete's heels are not supported, while wearing the many of the shoes currently in market. The athlete's heels sink into the ground, stressing muscles and tendons in the lower leg and foot. Thus, disrupting the anatomical alignment between the heel and toes.
Although some cleats may limit movement of the toes and provide an incremental enhancement of stability, it falls far short of the performance, ease, stability, and grip afforded by the subject matter disclosed herein.

SUMMARY

In accordance with one embodiment, footwear for receiving and supporting a foot of a wearer is provided. The footwear may have a front end, a rear end, a first side and a second side.
