1.What are puncture resistant shoes?

Puncture resistant shoes are a kind of foot protection work shoes worn by metal stamping, electroplating chemical industry, mechanical equipment manufacturing, printing and packaging, and steel shipbuilding production workshops and areas affected by the harsh external environment.

The puncture-proof midsole is placed on the top of the shoe sole to prevent sharp objects and sharp objects from piercing the sole of the shoe, thereby damaging the sole of the employee. Anti-piercing safety shoes are used to protect the soles of the feet and prevent injuries from various sharp objects. They are mainly used in mining, machinery, construction, metallurgy, logging, transportation and other industries. The hardness of the anti-puncture safety shoes is HRC52, the diameter is 4.Smm±25mm, the tip diameter is 1mm±0.02mm, the length of the steel nail is 60-70mm, the sole is pierced at a speed of 25mm/min, and the puncture resistance is greater than or Equal to 780N for safety purposes.

Accumulations in the workplace, such as the operation of mechanical equipment, transportation equipment, and the use of materials and tools, may cause the danger of nails, metal shavings or other sharp objects piercing or cutting the soles of workers. Damage is the same as mechanical damage. The types of industries and jobs that come into contact with machinery, tools, and materials are extremely common. In addition to the machinery industry, other industries such as transportation and storage have also suffered similar injuries.

2.The types of puncture resistant boots

Puncture proof work boots are mainly made by adding a layer of midsole protection between the sole and the upper, which mainly includes steel midsole and kevlar midsole.We need to understand the difference between steel midsole and kevlar midsole

2.1 Steel midsole VS Kelvar midsole

2.1.1 Steel midsole

  • Made of hard coated steel or stainless steel

  • Industrialized production, low cost

  • The thickness is about 1.5mm

  • Built-in structure: not seen when the insole is removed

  • Strong thermal conductivity

  • Suitable for small sharp objects in the working environment: such as iron nails

  • Poor flexibility, only slightly bent

  • Can not completely cover the part of the sole, the side part will be slightly exposed

  • When using coated steel, long-term use may cause the coating to fall off, induce steel corrosion, and reduce the service life

2.1.2 Kevlar midsole

kevlar-midsole

  • Made of aramid fiber textile cloth
  • Compared with the steel midsole, it is more elastic and comfortable
  • Lighter weight
  • Adopting a stitched structure: it is stitched together with the sole, when the insole is taken off, it can be seen
  • Non-conductive
  • It can be used in the working environment of warehouse, light industry and electric power
  • Belonging to the developing technology, it can also continuously update the material to achieve lighter and more comfortable purpose
  • Completely wrapped the bottom of the shoe
  • Has extremely strong wear resistance and longer service life

2.2 Steel and kevlar summary

The Kevlar midsole is a bit thicker than the steel bottom, and is more flexible than the steel bottom. It can be folded at will, so it has better comfort and softness. However, it also has a disadvantage that it does not have a steel bottom to resist puncture. Although its puncture resistance is not as good as that of a steel bottom, there is no problem when the nail blade is stepped on.
The steel midsole is cut from steel and added to the second layer. No matter what you step on, the sole will not pierce. It protects our feet very well. Although this steel sole can protect our soles, it feels less wearing, heavier and not so soft.

3.How to test the puncture resistance of safety shoes?

In order to let everyone better understand and choose safety shoes, the following introduces the common methods of nail resistant shoes performance testing.
Anti-puncture test
Put the shoe sole pattern on the chassis of the testing machine, and install the pressure plate and test nails on the testing machine. The test nail is a head with a truncated tip. The hardness of the nail head should be greater than 60HRC. Then the test nail is pierced through the outsole Until penetration, record the maximum force required, and select four points on each sole for testing. The distance between each point is not less than 30mm, and the distance from the edge of the insole is greater than 10mm.
Finally, let the editor introduce a few work boots with steel plate and steel toe kevlar midsole safety shoes.

This is a pair of classic leather safety shoes with puncture resistance midsole. As shown in the upper right corner of this picture, the midsole of this shoe is a steel-toed steel sole. The leather is a kind of artificial leather, not genuine leather. These shoes are relatively cheap, but they feel good on the feet. Recommended index is two stars.

4.2 Wearable puncture resistant steel toe shoes with PU outsole

Puncture resistant steel toe shoes steel toe added to the toe to a large extent increases the stability of the shoe, which will very well protect your toes from injury. The steel outsole is added to the midsole because there is a layer of insole on it, so it will not feel hard at all, and the foot will feel soft when stepping on it. The comfort is better, and the foot will not be tired even after walking for a long time. Mountain climbing, long distance, and rain are not afraid of anything. Three stars are recommended.

   Pros

   Cons

  • 1.Wearable leather upper

  • 2.puncture resistant midsole

  • 3.Clssic good looking
  • 1.Heavier

Most of the steel-toed steel midsoles are leather safety shoes, and most of the Kevlar midsole are safety trainers. Because safety trainers are mainly lightweight, breathable and comfortable. However, flying woven safety shoes are not waterproof. They are only suitable for spring, autumn and summer. Winter is not suitable. Some tropical rain forest climates prefer safety sneakers because they are softer and lighter with Kevlar midsole.

4.3Leopard light weight kevlar midsole safety shoes

Kevlar midsole safety shoes are here, light and breathable, soft and comfortable, the first choice for summer and tropical climate countries. Both beautiful and comfortable, black and beige are matched to make you the safest and most beautiful boy to the greatest extent. In the past, safety shoes were only designed in black. Now you wear safety shoes, even if you keep looking at the shoes, you can’t see the difference between safety shoes and sports shoes. Safety shoes with Kevlar soles are based on sports shoes with increased safety performance. Now some young people who love beauty and are doing high-risk jobs can choose safety shoes with Kevlar soles, which are beautiful, comfortable and light. The recommendation index is four stars.

4.4Breathable casual puncture protection work shoes

   Pros

   Cons

  • 1.Fashionable design
  • 2.Kevlar midsole
  • 3.Soft non slip outsole
  • 4.light weght upper

Bottom Line:

Kevlar is often referred to as bulletproof fabric fiber. The properties of Kevlar fiber are heat resistance, flame retardant, antistatic, acid, alkali and organic solvent resistance. Kevlar fiber also has high strength, high abrasion resistance and high tear resistance. It is precisely because of these characteristics that Kevlar has created the antistatic, fireproof and puncture resistance of safety shoes.

Some work shoes have steel soles. The steel plate in the midsole can isolate the impact from the sole and absorb the external force at the position below the steel plate, which will affect the sole of the foot, thereby obtaining better impact resistance. In order to make the shoes thicker and harder, please protect your feet when traveling outdoors. Therefore, a steel plate is added to the midsole of the shoe to increase the weight of the sole, thereby making the shoe more stable and better supporting the ground. Ordinary shoes have poor anti-slip performance because the soles are not wear-resistant, while shoes with steel plates are very wear-resistant and non-slip.

You can choose the puncture resistance safety shoes that suit you according to your working environment and needs.
