Core use: It is used for fire suppression of building structures and is an important part of firefighters' personal protective equipment sets.
Extreme protection:
Heat Insulation/Fire Protection: Multi-layer insulation materials (e.g. , Kevlar, rubber, leather) are used to withstand extremely high ambient radiant heat and direct contact heat for a long time, preventing heat conduction to the feet.
Waterproof/Sealed: Completely waterproof and sealed to prevent water, blood, chemicals, and other liquids from seeping in.
Anti-puncture: The middle of the sole is embedded with an anti-puncture baseplate (such as stainless steel, Kevlar material) to prevent the puncture of sharp objects such as nails, glass, and steel bars.
Anti-smash: A sturdy boot head (usually a composite or steel head) protects the toes from falling objects.
Anti-chemical corrosion: The outer fabric can resist a certain degree of acid, alkali, fuel and other chemicals.
Electrical shock protection: Provides some degree of electrical insulation, but is generally not suitable for high-voltage electrical work (that's a different type of boot).
Compliance with standards: Must comply with national or international mandatory safety standards, such as:
NFPA 1971 - National Fire Protection Association Standard
EN 15090:2012 - European Standard
GB 21147-2020 - Chinese standard for firefighter protective boots
Design features: high tube design (at least to protect above the ankle), quick piercing pull ring, reinforced heel, deep pattern outsole (non-slip V bottom is very common), etc.
