Description

Footwear for healthy standing and forefoot running {FOOT WEAR FOR HEALTHY STANDING AND FOREFOOT RUNNING}

The present invention relates to a footwear article, and more particularly, to a footwear article that can help promote health even when standing still.

Walking is a simple yet essential exercise for modern people for health. However, while walking healthy is good, healthy standing can be beneficial to your health. For example, just standing on your heels can help strengthen your calf muscles and improve blood circulation.

However, it is very difficult to actually stand with heels raised only on the forefoot, especially since elderly people with weak calf muscles may have an accident while doing this movement, so caution is required.

Registered Utility Model No. 20-0351293 discloses a shoe for diet. Diet shoes have a heel height higher than that of the heel, so when walking while wearing shoes, stand and move only with the heel part of the shoe, so that a lot of force is applied to the front part of the foot, and the lower body muscles such as the leg of the wearer are encouraged to walk. It explains diet shoes that can be exercised with only. In addition, Patent Publication No. 10-2011-0039163, Utility Model Registration No. 20-0410363, and Patent Publication No. 10-2014-0140302 also disclose a lot of shoes that make the forefoot thicker than the heel so that a lot of the heel is used when walking. has been

However, in shoes with this structure, it is very difficult and insecure to stand only on the forefoot when standing still. Of course, it can be said that standing on your forefoot is exercise because you are anxious, but an unstable posture contains the aforementioned risk of accidents.

The present invention provides an article of footwear capable of stably maintaining a standing posture with only a forefoot.

The present invention provides an article of footwear capable of assisting running using the forefoot.

According to an exemplary embodiment of the present invention for achieving the above-described objects of the present invention, in a footwear article including an upper and a shoe sole, an inclined surface is formed on the bottom surface of the forefoot of the shoe sole to become gradually thinner, and the front inclined surface Correspondingly, when the reinforcing core is attached or embedded in the surface or the inside of the sole of the shoe, and the wearer stands with an inclined surface in contact with the ground, the reinforcing core may support the forefoot and the anterior midfoot arch of the wearer's foot.

The reinforcing core is provided as a metal plate, which is embedded along the bottom of the shoe sole and can be bent between the inclined surface of the forefoot and the horizontal bottom of the hindfoot. In addition, it may be formed of a reinforced elastic material such as carbon fiber or TPU.

The reinforcing core may be provided to support up to the front of the hindfoot without extending to the rear end of the hindfoot. That is, since the reinforcing core is formed only from the forefoot to the front of the rearfoot, it does not prevent a pedestrian from walking, and can be usefully applied only when standing with an inclined surface in contact with the ground.

The reinforcing core can be bent in a Z-shape between the inclined surface of the forefoot and the horizontal bottom of the hindfoot, and can not only firmly support the arch of the foot in a standing position, but also provide improved repulsion properties during running.

In addition, the reinforcing core may be provided in the form of an arch or curved surface rather than a flat plate in front of the hindfoot.

The reinforcing core may include a plurality of ribs formed in the longitudinal direction to firmly maintain the bent shape and enhance elasticity, partially cut the reinforcing core and bend the incised portion in the wrong direction, that is, reverse the reverse bending. The bent portion may be further partially formed.

In the footwear article of the present invention, the reinforcing core supports only the front part of the user's arch from the forefoot, thereby providing stable support when the user stands on an inclined surface.

In addition, the user's forefoot and arch portions are naturally pressed toward the bent portion of the reinforcement core, thereby maintaining a more stable state.

In addition, the metal plate may act as a spring in a jump that generates a driving force after neutrality during walking to generate a stronger driving force. For this purpose, it is preferable that the metal plate is not deformed too flexible, and by using this characteristic, it is possible to provide excellent repulsion properties even when the heel does not touch, for example, even when the wearer runs on tiptoe.

1 and 2 , the article of footwear according to the present embodiment basically includes an upper 110 and a shoe sole 120 .

The shoe sole 120 includes a forefoot 124 that is formed to be gradually thinner by a relatively thick and flat hindfoot 122 and a front inclined surface 126 and has a relatively thin thickness compared to the hindfoot 122 .

Although the hindfoot part of other existing shoes is relatively thicker than the forefoot part, this is a thickening of the hindfoot part to alleviate the impact during the landing process of the foot, whereas the thickness difference in this embodiment is on the bottom surface of the forefoot part 124. By forming the inclined surface 126, it can be said that it is different from the conventional sole structure in that the rear foot part 122 is lifted when the ground is stepped on the inclined surface 126.

In addition, in this embodiment, it is characterized in that the reinforcing core 130 is provided on the shoe sole 120 in response to the inclined surface 126 rather than simply forming the inclined surface 126 in the forefoot 124 .

The reinforcement core 130 is formed along the bottom surface of the shoe sole, and may be formed only from the forefoot 124 to the front 128 of the hindfoot 122 . In this case, the reinforcing core 130 may be provided as a bent metal plate, and may be attached to the bottom surface of the shoe sole 120 or provided inside buried at a predetermined depth from the bottom surface.

Therefore, when the wearer stands with the inclined surface 126 in contact with the ground, the rear foot 122 naturally falls from the ground, and the reinforcing core 130 located in the front part of the shoe sole 120 is the forefoot ( 10) and the midfoot arch anterior portion 20 can be supported.

When the user is standing using the inclined surface 126, the reinforcement core 130 stably supports the forefoot 10 and the midfoot arch anterior portion 20 of the user's foot F, thereby strengthening the user's calf muscles and blood It can help promote circulation. In addition, the user's forefoot and the arch portion are also naturally pressed toward the bent portion of the reinforcing core, and the reinforcing core 130 is provided in the form of wrapping the user's forefoot and its periphery to maintain a more stable state.

In addition, since the reinforcing core 130 is provided locally only on the front portion of the sole 120 of the shoe, it does not interfere with the cushioning of the shoe during the landing process when walking. In multifaceted, the reinforcing core 130 , which is a metal plate, serves as a spring in a jump that generates a driving force after the neutral stage of walking to generate a stronger driving force. In addition, it is possible to provide stability to the wearer even when running by not touching the heel and stably supporting the arch of the forefoot and midfoot when running, where the forefoot is mainly used.

The reinforcing core 130 may be formed using a metal plate, but in addition, it may be formed of a material using carbon fiber, reinforced TPU, reinforced plastic, or the like.

3 is a view for explaining a reinforcing core that can be applied to a footwear article for healthy standing according to an embodiment of the present invention.

Referring to FIG. 3 , the reinforcing cores 130' and 130" may be provided in various shapes other than a simple flat plate. In the reinforcing cores 130' and 130", the front portion located in the front corresponds to the forefoot of the foot, and is relatively The posterior portion may be shaped and sized to support the arch portion of the metatarsal arch.

And may include a plurality of embossed or engraved ribs 132' that pass through the bent part in the longitudinal direction based on the bent part, and the rigidity and repulsion of the reinforcing core 130' by the ribs 132'. The elasticity can be further strengthened (a).

In addition to this, the other reinforcing core 130" may be partially cut and alternately bent to maintain the bent shape. Accordingly, a partially reverse bent reverse bent portion 132" may be formed. , it is also possible to further strengthen the rigidity and rebound elasticity of the reinforcing core 130" by the reverse bending portion 132" (b).
