A pair of comfortable shoes can bring people infinite happiness and joyful experience, but while pursuing beauty and fashion, the health problems of the feet cannot be ignored. Standing, walking and exercising for a long time will cause the legs to feel tired and Discomfort, and the degree of shock absorption of the insole is a key factor in the comfort of walking and sports.

So which material insole is more conducive to walking and sports?

Currently on the market, insole materials can be roughly divided into two categories: one is traditional insole materials, such as EVA, silica gel, ORTHOLITE, PU, ​​and the other is bionic metamaterials.

First introduce the traditional insole material:

EVA: EVA insoles are widely used and are commonly used in the midsole of shoes. However, the density of EVA made of insoles is lower, and the initial feeling is good. However, as time goes by, the soles tend to collapse. Basically, they are used in low-end sports shoes. .

Silicone: This kind of material is usually used in home slippers. Because it is relatively heavy, it is not easy to wick sweat, and it is relatively soft. At present, there are no brand sports shoes equipped with silicone material.

ORTHOLITE: This is the insole material commonly used in brand sports shoes. It has the characteristics of light weight, good cushioning, breathability and easy perspiration. It is suitable for daily walking, but it cannot meet the needs of high-intensity sports and people with heavy knee burden.

PU: A synthetic elastic material made of PU polyurethane material imported from Germany and modern design concepts. It is used as an insole with a harder foot feel and better stability. It is suitable for most basketball shoes and outdoor shoes. The disadvantage is that there is no drainage. Sweating ability, easily hydrolyzed when exposed to water.

The other material is bionic metamaterial. Currently, the only bionic supermaterial insole on the market is ACI artificial cartilage insole. The highlight of the insole is that the insole is built with ACF material. It has passed 12,000 failed experiments in the ACF laboratory for 6 years. Developed to imitate the structure of human articular cartilage, but better than human articular cartilage's shock absorption and buffering performance, it can absorb 98.7% of the impact energy transmitted from the ground to the knee, with high shock absorption and buffering, strong protection ability, and wraps the soles of the feet The ORTHOLITE material, auxiliary ACF material improves shock absorption and cushioning performance.

Also because of its excellent shock absorption performance, it has become a special insole for extreme sports and medical rehabilitation. For sports enthusiasts who love skiing, skateboarding, running marathons, playing basketball, playing badminton and other medium-to-high-intensity and extreme sports or professional athletes engaged in such sports, long-term and stressful foot activities are likely to cause knee joints, meniscus The wear and tear of bone tissue such as the waist, waist, etc., this kind of injury caused by improper prevention seriously affects their normal performance in sports. If they are accidentally sprained, it may even affect their sports career for the rest of their lives. The shock absorption and cushioning performance of ACF material is as high as 97.8%, which is 48%~97% higher than ordinary EVA insoles, 51%~102% higher than Polyyou insoles, and 46%~91% higher than pure aosolite insoles. It is the ceiling of shock-absorbing insoles. , While improving the sports performance, the impact damage is greatly reduced.

For those who suffer from knee arthritis, flat feet, foot valgus, foot surgery rehabilitation, daily walking is easy to cause foot fatigue, want to relieve foot and foot fatigue and pain, in addition to specific drug therapy or physical therapy massage , A more effective auxiliary rehabilitation method requires a pair of insoles with good shock absorption capacity. In addition to the built-in insole, the ACF material is also attached to the forefoot and heel to improve support and balance the force on the foot. In addition, the ACI artificial cartilage insole adopts shape memory and temperature deformation. When the sole temperature is transferred to the insole, the material will change. It is soft and the insole fits the shape of the foot better, making walking more comfortable.

In real life, many people will ignore the maintenance and replacement of insoles, thinking that it is a simple part that can be discarded or replaced directly, or that it is not as important as the style of shoes, but in fact, a good pair of shoes Insoles can be compared to a pair of exquisite shoes, and even its value is greater than that of shoes, because health and comfort are the ultimate needs for walking and sports.
