ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to athletic shoes and particularly to stabilizer athletic shoes for persons engaged in athletic activities. More specifically, this invention relates to an improved athletic shoes construction which incorporate features designed to increase foot and ankle stability during various athletic activities in order to decrease muscle fatigue, enhance performance and minimize injuries.
BACKGROUND OF THE INVENTION
Various athletic shoes are presently being marketed for different activities such as running, tennis, basketball, racquetball and golf. These shoes are designed to prevent, or at least minimize injuries caused by lateral foot ankle instability during such activities. Current athletic shoes do not adequately guard against injuries caused by all type of athletic activities, including those activities which involve side-to-side jumping motions. These activities have greater tendency for lateral foot ankle instability, and hence injury to the foot and/or ankle.
U.S. Pat. No. 3,738,373, issued Jun. 12, 1973 describes an athletic shoe which incorporates a flexible wedge mounted therein which extends completely to the rear edge of the heel thereby providing maximum “cushion”.
An earlier patent, U.S. Pat. No. 2,847,769, issued Aug. 19, 1958 discloses shoes for golfers which are designed to compel a golfer to automatically assume the correct golf stance.
Other athletic shoes incorporate air-cushioning means, usually in the heels, for absorbing the impact experienced during said activities.
So far as it is know, there is no single pair of athletic shoes which adequately affords the desired degree of protection and guards against injuries resulting from foot instability during athletic activities of the type hereinbefore mentioned. This is largely because the foot-angle structure is complex and includes numerous joint axis with different movements and displacements in response to varying impacts and positions. Thus, the design of an athletic shoe which can protect against the different possible injuries resulting from a variety of athletic activities must take into consideration such factors as supination, pronation, dorsiflexion, plantarflexion, abduction, and adduction which occur at the foot-ankle joint during said sports activities. Accordingly, there is need for a single athletic shoe which is designed to afford maximum benefits for those engaged in various athletic activities in which foot-ankle injuries are matter of common experiences.
It is therefore an object of the present invention to provide an athletic shoe which is designed to afford maximum protection against injuries resulting from sports activities involving jumping and side-to-side motions such as, e.g., running, jogging, basketball, tennis and racquetball.
It is a further object of this invention to provide athletes with athletic shoes which incorporate features that counter the adverse effects of such factors as supination, pronation, dorsiflexion, plantarflexion, abduction and adduction experienced by athletes during several athletic activities.
The foregoing and other objects of this invention will become more apparent from the following detailed description and accompanying drawings.
SUMMARY OF THE INVENTION
In accordance with the present invention an athletic shoe is provided which, because of its unique construction, assures dynamic foot stability, reduces lateral ankle instability and alleviate foot fatigue which often results from athletic activities such as jogging, running, tennis, basketball, jumping and even weight lifting exercises. In one embodiment, the athletic shoe comprises heel and a sole having a rear foot portion and a forefoot portion which has a medial section and a lateral section. The forefoot portion has a lateral wedge conformally affixed thereto or formed, integrally therewith, said lateral wedge member being tapered from the medial section toward the lateral mid portion of the forefoot.
In a second embodiment, the shoe is similar to the first embodiment and further includes a lateral heel stabilizer conformally attached to the heel counter, a medial heel wedge spanning the length and width of the shoe heel, and a tapered lateral forefoot member attached to the bottom sole of the shoe.
