The first consideration is to meet the performance. Generally, the appearance of work shoes is almost the same. The performance difference of most work shoes is reflected in the sole. The ground environment requirements determine the sole material. For example: casting, high temperature processing and other environments will make the ground temperature of the work area very high. High, high temperature resistant rubber soles are required. Machinery processing and other industries often make the ground splashed with oil, which is particularly slippery. It is necessary to use non-slip PU material soles to prevent slipping. There are sharp objects on the ground such as nails, glass, metal shavings, etc. in mines, fire fighting, construction, forestry, cold work, and machinery industries. At this time, it is necessary to add steel plates to the sole to prevent punctures, electricians, electrical operators, and cable installation Workers, substation installers, etc., have the risk of electric shock, and need to insulate the soles, and the working environment should keep the uppers dry. Avoid contact with sharps, high temperature and corrosive substances, and the bottom of the help must not be corroded or damaged. Gas station operators, liquefied petroleum gas filling workers, petrochemical company employees, there are flammable and explosive materials around, static electricity may cause fire and explosion, work shoe soles need a certain degree of conductivity to prevent static electricity from accumulating. If there are no special performance requirements, ordinary work positions only require anti-smashing, then PU soles are enough, light weight, soft, and comfortable to wear.
We first need to locate the main functional requirements, not all functions can be required at the same time, because the above various properties are sometimes not available at the same time, or even contradictory, such as insulation and anti-static functions, the requirements are completely opposite. And the more functions are required, the wearing comfort will decrease and the price will increase.
