Chelsea safety boots, featuring a lightweight fiberglass composite toe cap and Kevlar plate protection, full-grain cow nubuck leather, and a heavy-duty PU/rubber outsole. These comfortable and multifunctional lightweight boots suitable for Industry, Construction, Logistics, Mechanics, Oil & Gas, Chemical Plant, Power Yard, etc.
General information :
Composite Toe Cap Protection
It is made with light weight fiber-glass material, which can reach 200 joules from falling or rolling objects. It is stronger and lighter than steel toecap.
Kevlar Plate Protection
Kevlar midsole plate, is zero-penetration resistant. It can resist 1100 newtons nail puncture from sharp objects. It is stronger and more flexible than steel plate.
Full Grain Cow Nubuck Leather
Superior full grain nubuck leather with thickness 1.8-2.0mm. It is treated with breathable technology to keep feet from dry during walking all days. Tear strength is required 10% higher than Europe test requirement, to reach longer lifespan.
Heavy Duty PU/Rubber Outsole. The outsole is made with PU/Rubber material. The midsole is 45+5 degree hardness PU, which is soft and shock absorption. The outsole is natural rubber with 5%-10% nitrile, which can pass 300 °C heat resistant HRO test.
Insole memory foam: they take the impression memory of your feet shape, and provides cushioning to each part of your feet.
