Why choose outdoor sports socks

Update:02 Jul 2020

The feet of ordinary people will walk about 200,000 kilometers in their lifetime. When people walk, the weight of each foot exceeds 120% of the person's weight; when running, the weight of each foot even exceeds 300% of the person's own weight. When walking, especially in outdoor sports such as hiking and mountain climbing, people will find that their feet have blisters or calluses. This is mainly due to the improper cooperation between "socks", "feet" and "shoes".

Since the sock is in direct contact with the foot, it should have the most basic warming function, and the main function is to protect the foot, that is to reduce the friction between the foot and the shoe caused by walking, so the sock should be converted into Friction between feet and socks.

The feet should be attached as much as possible. The blistering and corpus callosum of the feet is because the socks are too thin or too hard, and the attachment to the feet is not close enough. Therefore, during walking, the friction between the socks and the shoes should be converted into Friction between feet and socks.

Therefore, socks specially designed for feet are very important in sports, especially outdoor sports socks. In outdoor sports, some people think that as long as the socks are thick, at least two pairs of cotton socks can provide adequate protection for the feet, which makes sense, because the two pairs of socks together can be better attached Attached to the foot, it reduces the friction between the foot and the sock and turns into the friction between the sock and the shoe.

However, in this way, another problem is ignored. After a long walk, the feet will swell 7%--8%, and the two pairs of socks will be tightly wrapped around the entire foot, even the ankle. The part of it is also encased, resulting in impeded blood circulation in the feet, which can cause some diseases of the feet. In winter or extremely cold areas, it will cause unnecessary frostbite.

So, what are socks specifically designed for feet? Let's start with the structure of the socks. First of all, there must be a pad, that is, there must be a towel-like loop at the bottom of the sock, so it is also called a loop. The main function of the terry is to increase the elasticity between the shoe and the foot, and at the same time, it also fully increases the area of ​​the sock material in contact with the air, so that it has better moisture absorption and perspiration, of course, the embodiment of the moisture absorption and perspiration Materials also have a lot to do. For different intensities of movement, the height, density and location of the loops should be different. In high-altitude mountaineering or long-distance walking, there should be loops on the soles and feet, and the height and density of the loops are the highest, so that the feet can be better played in all directions. protection. In middle-long-distance walking and low-altitude mountain climbing, general socks only need to add loops at the bottom of the feet, but the height and density of loops are still the highest requirements. Only in short-distance walking and logistics with ample supply, such as special travel and general travel, the height and density of the terry can be relatively low, but it is absolutely not necessary. Even general physical exercise, socks must also have terry.

Secondly, there must be a loop of elastic fixation at the arch of the sock, so that the sock can fit well on the foot. In the past, this kind of thing often happened: after walking for a while, the socks on the feet all ran to the front, or the socks turned sideways, and the bottom of the feet ran to the side of the feet, making the feet very uncomfortable. It is because the socks have poor adhesion to the feet, so by adding elastic fixation to the arch of the foot, you can avoid these kinds of things as much as possible. When the sole of the person's foot touches the ground, normally, the arch part touches the ground the least. When walking, the arch receives the least amount of friction. At the same time, this is the middle of the entire sole of the foot. It is most appropriate to add a fixation to this part. . Elastic fixation should not be too tight, too tight will affect blood circulation, nor too loose, otherwise it will not play a fixed role, socks will also run on the feet.

In addition, the toes and heels of socks must be thickened, the stress on the heel is the largest, and the toes are relatively weak places. Special protection is necessary. The joint between the tip of the sock and the foot surface of the sock must be flat and must not have ribs. This place is the position of the toes on the foot surface. If the seam is ribbed, it is easy to bruise the foot. This is the main part of the sock body, and then there is the part above the ankle. This part is basically exposed outside the shoes (boots), but there are certain special requirements. Let me talk about the ankle first. This part is generally the position of the upper, and a pad with a loop is still necessary, but because this part is the first position where the foot comes in contact with the air, the function of breathing must be reflected in the structure, generally on the front of the ankle The place where the tongue is in contact with the corrugated structure is slightly thinner than the terry structure, and the elastic material is added. Because the inner layer of the tongue is mostly made of foamed elastic material, which is softer than the material in other parts of the shoe and has less friction, the choice of the corrugated structure at this position will not cause damage to the foot. The ankle is the place where the script body moves the most, and the addition of elastic materials can ensure that the normal movement of the foot will not have too much sense of restraint. Above the ankle, if it is worn in winter or in an extremely cold environment, the waist of the socks should be relatively high, and some even below the knee, and the structure of the loops is required. In other environments, choose the middle waist. However, no matter whether it is a mid-waist sock or a high-waist sock, the part of the sock is the calf after all, so the structure of this part must adopt a structure with better elasticity, the elasticity should be moderate, and it is completely designed for the thickness of the calf. This is the basic structure of socks.
