How to buy safety footwear
Safety footwear is the collective name for safety and protective footwear, generally referring to footwear worn in different work situations that protects the feet and legs from foreseeable injuries. With the advancement of technology, safety shoes are becoming more comfortable to wear and more fashionable in appearance. Here we take a look at what aspects of safety shoes need attention.


One, according to the work environment to choose the function
Safety shoes should be selected according to the working environment, and the functional requirements for safety shoes vary from job to job.
The functions of safety shoes are: smash-proof, puncture-proof, anti-static, anti-slip, oil-resistant, high-temperature resistant and insulating.
Each industry generally has multiple functional requirements for safety shoes, so the regular safety shoes on the market are also compounded with multi-functional ones.
For example, pipeline construction workers are generally expected to wear safety shoes that are acid and alkali resistant, oil resistant, slip resistant and waterproof. Building construction workers have a more complex working environment and will want different functional shoes for different jobs, with the most needed functions being smash-proof, puncture-proof and slip-proof. The electrical sector or power operations choose to need electrical insulation features.
Second, the safety shoes sole examination
Safety shoes are divided into rubber and PU soles.
Rubber soles are also divided into natural virgin rubber and synthetic rubber, virgin rubber is made from rubber trees, rubber grass and other plants after the extraction of gum, synthetic rubber is made from various types of rubber raw materials and chemical composition processing. The former is more valuable than the latter due to its natural scarcity and environmental friendliness.
Rubber soles are resistant to hydrolysis, oil, heat, weak acids and alkalis, and rust, and are suitable for harsh environments.
PU (collectively known as polyurethane) was first used as a sole material in the 1970s. PU soles are softer and lighter than rubber soles, more flexible but more prone to corrosion when wet and less wear-resistant than rubber soles.

Safety footwear technology is divided into single density PU soles, dual density PU soles and the now very popular PU+rubber soles.
Single density PU soles are relatively less tough and flexible than dual density PU soles, and have a much shorter service life. Double PU soles are lighter, more wear resistant and have a longer life than single PU soles, and the workmanship is more complex than that of single PU soles.
PU + rubber soles can be considered the most practical type of safety shoe sole on the market today. It gets rid of the bulkiness of the traditional rubber outsole and makes up for the shortcomings of the PU outsole in terms of wear resistance and puncture resistance, retaining the comfort and softness of the PU elastic layer and increasing the wear resistance and puncture resistance of the rubber sole, greatly extending the damage cycle of the sole.
If you are looking for safety shoes with anti-slip properties, you should consider the material and density of the sole, and also analyse the design of the sole pattern.
Second, the requirements of the leather upper of safety shoes
First and second layer leather
Genuine leather safety shoes can be divided into two categories: first layer leather and second layer leather. First layer leather is animal leather such as cow, sheep and pig skin with grainy surface, the leather surface is natural and some still have processing and cutting marks. The second layer of leather is a two-layer part with a looser fibre tissue, sprayed with chemical materials or covered with pvc or pu film. Depending on the nature of the two, we can pull the leather hard and see tiny pores and deformation on the surface of the skin, while the second layer has no pores and no visible deformation. The first layer of leather is more breathable than the second layer, while retaining the original leather pores.

Suede and Fleece
Suede, also known as game leather, is a leather that has been polished to a pile-like surface. The concept of suede and retrimmed leather can be considered almost identical, characterised by an uneven surface and a strong suede feel, with the front and back of the leather feeling similar to each other.
Brushed leather
Brushed leather is generally made from the surface of the first layer of cowhide by lightly grinding, the surface is uncoated, slightly velvety, the leather surface is flat and the two sides of the leather layer are completely different, it is more expensive than reversible leather.

Embossed leather
Embossed leather is made from cowhide that has been pressed with a steel pattern plate to produce a pattern effect, and can be divided into first layer embossed leather and second layer embossed leather.

PU leather
PU leather is called microfiber simulation sofa leather, also known as artificial leather, recycled leather, or microfiber leather, leather grain and leather similar, feel softer, ordinary consumers eye view is difficult to distinguish between genuine leather or artificial leather. Belong to the synthetic leather in a new development of high-grade leather, not genuine leather.

Third, the choice of safety shoes anti-smashing head
The smash-proof toe is divided into a steel toe, a plastic steel toe and a new type of toe made of composite materials.
The steel toe is heavy and the plastic toe is lighter. Under the same index, the two types of head are equally resistant to compression. However, under the same impact, the shape recovery ability of the plastic head is better than that of the steel head, so the plastic head is more durable in comparison.
As steel is electrically conductive, there are generally more insulated safety shoes with a plastic toe, but steel toes can also be used in insulated safety shoes after being wrapped in insulating material.
Four, safety shoes tongue of the different
The tongue of safety shoes is divided into a split type and a one-piece tongue. Split tongue is commonly used in travel shoes and running shoes, tongue and upper separate tongue can move freely up and down or left and right; and one-piece tongue according to some work environment needs, in order to prevent the tongue left and right shift and the tongue and upper is connected together, help to prevent wind and sand, but the comfort is poor than split tongue.
