How to choose a sports insole? How to choose a running insole

Mainly depends on his softness.

What material is best for sports insoles.

What material is best for sports insoles.

Athletic insoles are mainly shoe materials with unique characteristics in terms of elasticity, sweat absorption, shock absorption, comfort, etc., and are more suitable for the physical properties required for the shoe materials of sports shoes.

When people exercise, they are all done through the strength of the feet, so that there is a relatively large load of impact concentrated in the feet; In addition, the feet produce a lot of sweat, and the growth of bacteria in the feet reduces the comfort of the foot environment. The soles of most sneakers have the characteristics of shock absorption and high elasticity, but it is obviously not scientific to rely on the sole to improve the comfort of sports. This brings a problem to the insole processing manufacturers, the shock absorption can not affect the elasticity, and the shock-absorbing materials such as memory foam obviously cannot meet such requirements; In terms of material selection, after testing various materials, we have come up with the following two material suggestions:

1: High-density sponge: this kind of material is used for insole processing, which solves the problems of sweat absorption, breathability and shock absorption; In addition, these materials also have a strong high elastic performance.

2: High-density pull back EVA: Although the air permeability of this material is poor, the resilience and flexibility are higher than other materials, and the shock absorption performance is also very good, so it can be used as a preferred material.

The above two materials are also very good in terms of anti-slip properties, which is why the materials in sneakers are usually the first choice for the above two materials. In the process of insole processing, how to better improve the above-mentioned physical properties needs to be further explored.

However, the insoles are generally only suitable for walking, not for running. The size of the insoles required for running is a little higher than that of general insoles. Runners need to find the right insole for their foot shape.

Of course, this insole also has to match the shape of the running shoe. If the insole doesn't fit, then there will be an embarrassing scene where the insole squirms out of the running shoe during a run.

So how should runners choose insoles? What are the characteristics of a pair of running insoles?

First of all, the insoles should fit your feet, and there are different designs depending on the foot.

The second is to have good breathability, if you accidentally step on a puddle during a run, it will be very uncomfortable.

Third, the insole should have a certain amount of friction. Avoid slipping your feet in your shoes to reduce injuries during exercise.

Fourth, the insole should have a certain cushioning force. Although the insoles are designed to be a bit thin, they must be cushioned to reduce damage to the knees when running. It also has a great improvement in the feeling of the feet for running.

Generally, the insoles we bring when we buy shoes are not necessarily the best, but they must be the most suitable for that pair of running shoes. When you buy shoes, you also like the feel of those shoes, so the original insoles are a good choice.

Many sports brands have self-designed running insoles, which generally come in three materials.

The first is silicone material, the insole of this material is generally soft, and the cushioning is better, but the biggest problem of the insole of this material is that it is not breathable. So it's not recommended to choose.

The second material is Ortholite, which has the characteristics of breathability, sweat absorption, odor resistance, mildew resistance, cushioning and good air permeability. This kind of insole is generally not much different from the original insoles, and it also has good elasticity and wear resistance, so it is recommended to pay more attention.

The third is multi-piece material, emphasizing the main feature of the functional running insole is that it is made of multi-material splicing, which is also specially designed for running, and the heel and forefoot are cushioned with material. This kind of insole will weigh a little more, and it will be a little higher. However, this type of insole is not suitable for lightweight running shoes with good wrapping and running shoes with limited size.

The fourth is the up-material insoles, which are synthetic materials, which are very strong and durable, and inexpensive. This insole does not harden and become brittle. Now there are many enterprises that have started to produce multifunctional insoles from this material.
