Structure of Socks

To know what kind of socks fit, this requires understanding the structure of the socks. The socks are composed of cuff, sock leg and sock foot. The sock foot includes heel, foot and toe. The function of cuff is to prevent the edges of the sock from falling apart and to fit tightly on the legs. There are 4 main parameters of socks: cuff width, cuff length, leg length and foot length. In the selection process, we cannot measure one by one, but from the following aspects, we can roughly determine which socks are fit.

Firstly, there must be terry. The main function of the terry is to increase the elasticity between the shoe and the foot. 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 manifestation of moisture absorption and perspiration has a great relationship with the material. For different intensity exercises, the height, density and location of the terry should be different. In high-altitude climbing or long-distance walking, there should be terry on the foot, and the height and density of the terry are the highest, such as whole-terry custom athletic socks. So that the feet can be better got protection. In long-distance walking and middle-low altitude mountaineering, generally socks only need to add a terry at the bottom of the foot, such as half-terry custom athletic socks. But the height and density of the terry are still the highest. Only in short-distance walking or walking with abundant logistics supplies, such as special travel and ordinary travel, the height and density of terry can be relatively low, but it must not be absent. Even in general physical training, custom socks must still have terry.

Secondly, there must be a loop of elastic fixation on the arch of the socks, so that the socks can fit on the feet well. In the past, this kind of thing often happened: after walking for a while, all the socks on the feet went to the front, or the socks turned sideways, making the feet very uncomfortable. It is because of the poor adhesion between socks and feet. Therefore, by adding elastic fixation to the arch area, you can avoid such things as much as possible. When the feet touch the ground, under normal circumstances, the arch area touches the ground the least, and when walking, the arch receives the least friction. At the same time, this is the middle of the foot, it is most appropriate to add a fixation to this area . The elastic fixation should not be too tight, too tight will affect the blood circulation, and it should not be too loose, otherwise it will not work as a fix, and socks will run on the feet.

In addition, the toes and heels of socks must be thickened. The heel is the most stressed, and the toes are relatively weak. Special protection is necessary. The splicing of sock foot and toe must be flat and must not be edged. This place is the toe position on the foot. If the seam is edged, it is easy to bruise the foot.

Lastly, sock’s ankle. This part is generally the upper position, and a terry pad still necessary. This part is the first place where the foot contacts the air, the ventilation function must be reflected in the structure. Usually on the front of the ankle, the contact with the shoe tongue uses a corrugated structure that is slightly thinner than the terry structure, and add elastic material at the same time. Because the inner layer of the shoe tongue is mostly made of foam elastic material, it is softer than the material in other parts of the shoe, and the friction is less, so the corrugated structure will not hurt the foot in this position. The ankle is the place where the foot moves most. Adding elastic material can ensure that the normal movement of the foot will not have too much restraint.
