Description

Footwear that induces correct gait {FOOTWEAR LEADING INTO RIGHT GAIT}

The present invention relates to a footwear article for correct gait, and more particularly, to a footwear article that can induce a healthy gait while beneficial to the human body.

Shoes started out as a purpose to protect the feet, but as the related technology develops, various purposes and functions are provided. For example, unlike in the past when various exercises were performed with a pair of sneakers, recently, according to the needs of users, specialized Functional footwear is being developed.

In general, shoes largely include an upper part that protects the instep and joints, and a sole part that protects the sole of the foot, and the sole part is attached to the midsole and the bottom of the midsole for absorbing shock. It includes an outsole for abrasion-resistance and anti-slip properties. Recently, the midsole and the outsole are combined into one material, and in some cases, they are provided as one without separate separation.

A healthy gait may be good for a natural progression of landing, neutral and forward. However, walking with the heel lifted due to the use of high-heeled shoes or soles is affecting the walking habits of modern people.

Patent Publication No. 10-2005-0007242 discloses a "rear balance walking shoes". The second balance walking shoe has a double ground axis formed from the center of the shoe sole to the rear axle, and the front axle and the rear axle are formed to be inclined upwards around the double ground axis. It is said that the part and the heel part can be formed to flow up and down. As a result, the center of gravity of the human body is shifted to the rear, which activates the trunk muscles by the rear balance to relieve obesity.

Registered Utility Model No. 20-0198016 discloses "weight-variable shoes". The variable weight shoe discloses a shoe that can change the weight of the shoe, such as a sandbag for leg muscle exercise.

According to an exemplary embodiment of the present invention for achieving the above-described objects of the present invention, an article of footwear for correct gait including a sole and an upper is an air cushion positioned at the rear of the sole to form a part of the sole. And it includes an inlet for the fluid to enter and exit the air cushion, it is possible to induce the power gate according to the weight of the fluid filled in the air cushion.

The interior of the air cushion may include a lower portion, a middle portion, and an upper portion, the lower portion may have a smaller area than the central portion, and the center of the lower portion may be located behind the center of the middle portion. Accordingly, the fluid to be filled in the air cushion is first located in the lower portion, and its center is located in the rear so that the overall center of gravity is located in the rear.

The inlet may be located on the top of the air cushion, and the user may inject the fluid into the air cushion through the inlet, and if necessary, discharge the fluid to the outside or all of it. It drains the fluid, and the air in the air cushion can absorb the impact and provide repelling properties.

A fluid may be injected or discharged into the air cushion through a predetermined injection device corresponding to the injection hole. To this end, the injector may include a nozzle corresponding to the inlet, and in a state in which the nozzle is coupled to the inlet, the fluid may be injected into the injector through the injector or the fluid may be discharged to the outside.

In this embodiment, the inlet and a portion of the air cushion around the inlet may be exposed to the outside, and the inlet may be preferably located in the upper center of the rear.

For reference, as used herein, the fluid may be oil or other fluids as well as general water.

The footwear article for inducing a correct gait of the present invention can induce a stable landing while walking, and can allow the heel to first contact the ground during the landing process.

In the footwear article for inducing the correct gait of the present invention, the strength of the power gate can be adjusted according to the user's needs by adjusting the amount of fluid filled in the air cushion.

In the footwear article for inducing a correct gait of the present invention, even if the air cushion is not filled with a fluid, it may act as an air cushion that acts as air itself.
