Description

Shoe pad structure

Technical Field

The present invention relates to an insole structure, and more particularly, to an insole structure made of materials having different densities and supporting effects.

Background

Generally speaking, the main difference between the children's foot and the adult foot is that the ossification of the foot bone of the child does not develop completely, resulting in unstable arch, but is plastic, and from the beginning of growth, from embryo to birth, and continues until the adult stage, the calcification of the foot bone starts from the outside of the rear part of the foot to the inside of the front part of the foot, while the earliest recognizable bone nucleus is tarsal bone appearing in the heel part of the foot at 5 and 6 months of pregnancy, two more bone nuclei appear in the talus at 7 and 8 months, and the bone nucleus of the cuboid bone is clearly visible at birth, and as the foot grows, the arch gradually forms.

In the infant stage of 0-3 years old, the feet of the baby are smooth and elastic, 70% of the bones of the feet are cartilages, and the feet have no arch form and belong to flat feet. In the critical stage of 3-6 years old, the foot bones begin to ossify, the arch of the foot is formed, the flat foot is slowly changed into a normal foot, and the standing posture, the walking habit and the shoe wearing of a child can influence the shaping of the arch of the foot, so special attention is needed. When the children are in the mature period of 6-12 years old, the bones of the feet of the children grow gradually mature, the arch forms are gradually closed from the development period to the stabilization period, the palmar prints are increased, the stability is good, the plantar longitudinal arch of the children is formed only after the children are 4 years old, the plantar longitudinal arch grows together with the bones, and the mature arch shape is formed after the children are about 10 years old; the foot morphology develops completely mature until age 13 and the arch forms, but at this stage it is necessary to avoid severe physical activity and trauma and lesions, and the arch shape of a person can be roughly divided into a normal arch, a high arch and a flat arch, and the normal arch shape can play a role in stabilizing balance and shock absorption for sports, but the high arch and the flat arch can have corresponding influences in different degrees.

However, the general insole is not designed to fit the sole of a baby or a developing adolescent and at the same time can effectively provide an insole structure having a supporting effect.
