Insole structure

technical field

The invention relates to an insole structure, in particular to an insole structure composed of materials with different densities and each having a supporting effect.

Background technique

In general, the main difference between the child's foot and the adult's foot is that the ossification of the child's foot bones is not fully developed, resulting in an unstable but plastic foot arch that begins with growth, from embryonic to birth, and continues into adulthood. So far, the calcification of the foot bone starts from the outside of the back of the foot and ends on the inside of the forefoot, and the earliest identifiable bone nucleus is the tarsus of the heel at 5 or 6 months of pregnancy. At 8 months, two more bone nuclei appeared in the talus, and the bone nucleus of the cuboid bone was also clearly visible at birth, and the arch of the foot gradually formed as it continued to grow.

In the infant period of 0-3 years old, at this stage, the baby's feet are round, smooth and elastic, 70% of the foot bones are cartilage, and there is no arch shape. At this time, it belongs to flat feet. In the critical period of 3-6 years old, the bones of the foot begin to ossify and the arch of the foot is formed. At this time, the flat foot will gradually become a normal foot. The standing posture, walking habits and wearing shoes of children may affect the arch of the foot. molding, so special attention is required. At the mature stage of 6-12 years old, the skeletal development of children's feet gradually matures, the shape of the arch of the foot gradually moves from the developmental stage to the stable stage, the palm lines increase, and the stability is good, and the longitudinal arch of the foot of the child will be formed at the age of 4. Along with the growth of the bones, a mature arch shape is formed around the age of 10; until the age of 13 or more, the foot morphology is fully mature and the arch is formed. The arch shape can be roughly divided into normal arch, high arch and flat arch, and the normal arch shape can play a role in stabilizing balance and shock absorption for sports, but high arch and flat arch will produce correspondingly different degrees.
