The present disclosure relates to a padded shoe for body balance adjustment by body type and, more particularly, to a padded shoe for body balance adjustment by body type that induces a posture in which the heel is maintained at 90° to the ground, so that the calcaneal angle is neutral, which is the resting calcaneal stance position (RSCP) angle, when upright, thereby maintaining overall body balance by allowing an attachment pad with a material, thickness, and hardness set to suit the user's foot condition to be attached to a set area on the surface of a shoe sole.
Feet are one of the most essential parts of the body for balance, and in order to maintain overall body balance, it is important to first maintain the balance of the feet in a neutral position and keep the heels at 90 degrees from the ground. If the feet and ankles are not balanced, the body may become distorted and deformed.
Moreover, even though the pressure of each region of the foot is different, most outsoles and midsoles of shoes have the same hardness throughout the sole. Thus, a shoe wears out easily on the high-pressure regions of the sole of the foot, and after a certain period of time, the difference between the worn areas and non-worn areas increases, causing the foot to become more distorted. When the wearer continues to wear shoes with asymmetric sole wear, the imbalance in the body becomes more severe.
Technologies to compensate for these shortcomings are being researched. Examples of such technology include Korean Patent Application Publication No. 10-2005-0122205 “METHOD AND APPARATUS FOR IMPROVING HUMAN BALANCE AND GAIT AND PREVENTING FOOT INJURIES” and Korean Patent No. 10-1557782 “ORTHOTIC FOOT DEVICE WITH REMOVABLE COMPONENTS SUPPORT AND METHOD OF MANUFACTURING SAME”.
The apparatus of the first example consists of an electrode or a vibration actuator, an insole, a sock, a shoe, a shoe insertion member, a platform, and a control device to generate non-deterministic random signals and repetitive pattern signals, which may improve foot sensation and blood flow and promote therapeutic effects. However, external stimulation is needed and there are limits to the effectiveness of maintaining body balance during normal walking.
The device of the second example consists of a flexible insole sash, an arch support member, a metatarsal support member, a cushion layer, and an intermediate attachment concave part, which may improve comfort and wearability. However, there are limits to maintaining body balance by manufacturing shoes that fit an individual's body type and characteristics.

Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the related art, and the present disclosure is intended to provide a new type of padded shoe for body balance adjustment by body type, which guides the heel to maintain a 90° angle to the ground (RCSP) to make the balance of the foot neutral by allowing an attachment pad, such as a medial longitudinal arch pad, a medial heel pad, a lateral heel pad, a cuboid pad, and a metatarsal pad, with material, thickness, and hardness set to suit the user's foot condition to be attached to a set area on the surface of a shoe sole.
Furthermore, an objective of the present disclosure is to reduce pain by reducing pressure on the plantar fascia and to help the wearer walk normally.
In order to achieve the above objective, according to an embodiment of the present disclosure, there is provided a padded shoe for body balance adjustment by body type that maintains body balance by correcting pressure on a sole of a foot, the shoe including: a shoe body 200 having a shoe sole 100 in contact with a user's foot; and an attachment pad 300 attached to a setting area of a surface of the shoe sole 100 to protrude upward and has a material, thickness, and hardness set according to a condition of the user's foot, wherein the attachment pad 300 may consist of one selected from the group of a connection pad, a calcaneus pad 350, and a metatarsal pad 360, wherein the connection pad may consist of: a medial longitudinal arch pad 310 disposed on an inner edge of a midfoot corresponding to a foot arch, convexly formed in a half-moon shape or a streamlined shape, made of a hard material, and formed to a thickness corresponding to a height at which the foot arch has collapsed to perform a function of raising the collapsed foot arch; a medial heel pad 320 arranged to be connected to the medial longitudinal arch pad 310, disposed on an inner edge of a hindfoot corresponding to the foot arch, convexly formed with a curved line, made of a hard material, and performing a function of straightening a heel that has collapsed inward to a neutral position; a lateral heel pad 330 arranged to be connected to the medial heel pad 320, placed on an outer edge of the hindfoot in response to the foot arch, convexly: formed with a curved line, and having an edge thickness corresponding to an angle at which the heel is collapsed; and a cuboid pad 340 arranged to be connected to the lateral heel pad 330, placed on an outer edge of the midfoot, convexly formed in a dome shape, the calcaneus pad 350 may be placed in a rear central portion of the midfoot and a front central portion of the hindfoot corresponding to a calcaneus, and may be convexly formed in a circular or an oval shape, and may be made of memory foam materials to absorb a load imposed on the calcaneus, thereby reducing pain caused by lipoatrophy, and heel pain caused by mid-bone spurs and plantar fasciitis, and the metatarsal pad 360 may be disposed on a rear portion of a forefoot and a front portion of the midfoot corresponding to metatarsal bones, may have a “∧” shaped toe support end formed convexly in an area between a big toe and an index toe, may be made of a material with bounce characteristics, and may guide the big toe to be positioned straight to provide a repulsive force to the big toe when the heel is lifted while walking, thereby inducing normal walking, wherein the calcaneus pad 350 may be divided into a plurality of pieces to correspond to a shape of the calcaneus.
In this case, the calcaneus pad 350 may be formed in a shape corresponding to the shape of the calcaneus by consisting of a central portion 352 and a plurality of side portions 354 of different heights or hardness that surround the central portion.
In addition, a bridge pad 370 may be further provided to connect the calcaneus pad 350 and at least one of the medial longitudinal arch pad 310, the medial heel pad 320, the lateral heel pad 330, and the cuboid pad 340 of the connection pad, thereby distributing the load received by the calcaneus pad.
In addition, the shoe body 200 may be divided into six division regions 110: a medial forefoot region, a lateral forefoot region, a medial midfoot region, a lateral midfoot region, a medial hindfoot region, and a lateral hindfoot region, and any of the division regions 110 where the attachment pad 300 is to be placed may be selected according to a user's foot type corresponding to individual division regions 110, and the attachment pad 300 having hardness and thickness set for each selected division region 110 may be placed in the corresponding division region 110.
The attachment pad 300 may be made of any one material selected from the group of a material with bounce characteristics, a memory foam material, and a hard material, and the material may be selected according to the user's foot type corresponding to individual division regions 110.
The attachment pad 300 may be placed in the division region 110 selected to correspond to each of ten abnormal foot types, and a combination of one or more attachment pads 300 having hardness, thickness, a shape, and a material set to suit each of the abnormal foot types may be disposed in the shoe body 200, wherein the ten abnormal foot types may include a normal foot hindfoot valgus type, a normal arch with excessive hindfoot valgus type, a normal arch hindfoot varus type, a flat foot neutral alignment type, a flat foot hindfoot valgus type, a flat foot with excessive hindfoot valgus type, a hollow foot neutral alignment type, a hollow foot hindfoot valgus type, a hollow foot with excessive hindfoot valgus type, and a hollow foot with excessive hindfoot varus type.
According to the above-described technical solutions, the following effects can be expected:
First, an adhesive pad is attached to the surface of the sole to ensure that the alignment of the heel is close to neutral, allowing normal walking and overall body balance to be maintained.
Second, abnormal foot types other than the neutral (normal) foot type can be maintained in a type close to a normal foot.
Third, pressure or strain on sore points of plantar fasciitis in patients with plantar fasciitis can be reduced, and a walking pattern of a patient with plantar fasciitis can be improved to restore a normal gait.
