Description

Shoes having functionality

The present invention relates to a functional shoe, and more particularly, to a functional shoe to which the foot support is adjustable height.

In general, the shoe serves to mitigate the impact force transmitted by the weight when walking to the spine or the like.

As the most ideal way of walking, walking on the floor from the heel to the sole of the foot to the root of the big toe is known as the "triple" walking method.

However, the conventional shoe is applied to the sole made of a flat, the weight of the weight is concentrated on the heel of the foot when walking, the impact force is transmitted to the spine, etc., causing a burden on the waist, shoulders, neck, etc. as well as causing pain The toes are deformed and the connection of the foot is not supported, so flat feet are induced, and three-time walking is not performed, and there are various problems such as increased fatigue.

In order to solve this problem, in Korean Patent No. 239854, front and rear incisions are formed on the front and rear portions of the shoe sole, respectively, so that three-time walking takes place naturally, and fatigue is significantly reduced while acupressure and The blood circulation function was performed, but the arch of the foot (footbow) was not supported, and the rear incision caused the area of the back to reach the ground, so that there was a problem that the body was not balanced.

In Korean Patent No. 556050, the heel is inclined in two stages to have a first ground plane and a second ground plane, and at the same time, the bottom surface is defined by a boundary between the front heel and the heel and a boundary between the first ground plane and the second ground plane. In order to be inclined upward, the three-time walking was performed accurately while walking, but the arch of the foot was not supported.

In order to solve these problems, in Korean Patent No. 851537, the foot arch support is inserted into the connection portion of the shoe sole, so that the user corrects the arch of the foot when walking to induce the development of the correct foot, and the rolling motion of the foot is naturally maintained. In order to prevent the deformation of the foot and the disease by distributing the load due to the weight, in the sole of the shoe consisting of the first half, the second half and the connecting portion connecting the first half and the second half, the foot portion is inserted into the foot support, the foot arch support Discloses a shoe sole inserted to be positioned from the inner end to the center of the connection.

However, since the height of the foot arch support is determined, there is a problem that it is difficult to fit all the foot arches of different sizes.

Meanwhile, Korean Patent Publication No. 2002-7662 fixes a pedestal with a screw hole in the center to an upper portion of the middle window, and forms a height adjusting screw hole in the middle window to turn the height adjusting screw screwed to the screw hole of the pedestal with a screwdriver. Disclosed is a flat foot fixed shoe having a structure for adjusting and for arranging a plurality of support springs around a pedestal to form a natural oval convex.

However, the user feels uncomfortable because the support of the foot arch is supported only by the screwing of the height adjustment screw, and the support spring assists the foot arch as an auxiliary but the support spring may collapse by weight in actual application. There is a problem that large. In addition, there is a disadvantage that the structure is complicated by the increase in the number of parts as a whole by applying the support spring.
