1. Don't choose socks made of 100% cotton. Because the abrasion strength of socks mainly depends on the inner yarn, which is the elastic yarn inside the socks, such as spandex, nylon, etc. How to distinguish? It is very simple. First, look at the ingredients on the trademark. Spandex is the best, which is stronger than nylon. The second is to grab the sock and pull it straight. The elastic one has the inner yarn.
2. Some socks are head-heel reinforced, which means that the toe and heel of the sock use more raw materials. Of course, such socks are not easy to break. You can find them in small stores of foreign trade surplus. When you buy it, touch it to see if the toe and heel are thicker than the sock body.
3. Generally speaking, thick socks are firmer (not to mention but also know), the same thickness, blended (acrylic cotton) is firmer than cotton, cotton is older than acrylic, and acrylic is firmer than wool.
