Description

Decompression insole structure

technical field

The utility model relates to a decompression insole structure, in particular to an insole structure which conforms to the motion state (dynamic or static) of the human foot and can guide the stress dispersion smoothly to reduce the pressure of the foot.

Background technique

At present, most of the original insoles are attached to the shoes. Most of them are flat insoles of equal thickness. Some may have a little more arch thickness to increase support. Stabilize the hard block; then, install cushioning rubber blocks in the places where the foot pressure is the greatest, that is, the heel and forefoot to reduce the impact from the ground, but the cushioning rubber blocks instead form resistance during travel, waste kinetic energy, and increase the travel time. applied force.

The following describes the three steps of the normal gait process: Please refer to Figure 10. In step (1) in the figure, the foot position is in front of the body and the outer soles are on the ground, offsetting the oblique power, bearing the vertical gravity, and transferring the forward thrust. Then, go to step (2) the internal rotation of the sole of the foot is transferred from the outside, and the stress is continued to the inside, and the foot position is moved to the back of the body during this process; then go to step (3) in the ball of the thumb to receive the accumulation in the previous step. The forward thrust is transmitted, and a new thrust is injected into the sole of the foot, and then the pedal kicks out explosively, thus completing a complete and good walking dynamic. It can be seen from the above gait process that the soles of human feet are not the most suitable for exercise when stepping on a flat surface. This is also the main reason why the foot damage is uncomfortable in the world today, the population with collapsed foot arches is only increasing, and the proportion of children with flat feet has risen sharply; further, the pressure of the foot arch already exists when standing, plus The damage to the arch of the foot can be imagined by walking or running for a long time, so the flat pedaling environment is not suitable for human walking at all.

For a pair of sports shoes with good performance, the tread angle and curve of the bottom of the sneakers are the key factors, and the design of general sneakers ignores this extremely important key, although some sneakers forefoot air cushions and thick-soled insoles can be compressed by these materials themselves. However, during lateral movement, the physical phenomenon of the insole tread and the bottom position of the insole are dislocated up and down, causing the sole to turn out easily. In addition, the high-thickness insole 5 is a bonus in terms of the function of shock absorption, but if the high-thickness insole 5 is to obtain a suitable force angle on the ground, it will be resistance and hinder the most appropriate settlement of the sole of the foot. 5 After lateral dislocation, when the bottom arc of the inner top height stops or changes direction laterally, the sole surface of the shoe is higher than the ground, causing the inner height of the sole of the foot to be valgus (as shown in Figure 11), which is not only difficult to maintain stability. In order to balance the movement of the body, it is necessary to increase the force on the outside of the ankle to balance, and the increase of muscle load will also increase the chance of sprains, and the soles of the feet will slide to the outside to be difficult to support.
