This is a domestic product that is a complete imitation of foreign hiking shoes. The pinyin seems to be "gnaw my tribe". Generally, regular warm hiking shoes have a logo under the tongue label that says "Thinsulate". This is Thermal insulation material produced by the American company 3M. If the hiking shoes have this label, it means that the thermal insulation performance is good. But what is "insulated"? I really don't understand. What’s even more strange is that there is a line of GOODYEAR WELT below, which is really wrong. GOODYEAR WELT technology is usually used in high-end leather shoes. How can it be used in hiking shoes? In this case, the price is very cheap, with a cap of 250 yuan.
