(1) Insulated Shoes

Insulated shoes are designed to minimize the risk of electric shock. Since an electric current passes from the contact point through the human body to the ground during an electric shock, insulated gloves and insulated shoes must both be worn for electrical work. Insulated shoes are available in voltage grades of 18KV, 6KV, and 5KV, and should be selected according to the operating voltage range. They require regular inspection and maintenance; once damp or severely worn, they will no longer provide effective insulation protection.

(2) Safety Shoes

Also known as toe-protective anti-smash shoes, safety shoes are mainly used to prevent foot and toe injuries from falling or striking objects. Examples include being hit by rolling drums, heavy pipes, or accidentally kicking sharp metal plates when handling heavy objects or loading/unloading materials. The toe cap is lined with lightweight, high-strength materials with excellent impact resistance, which must pass standardized performance tests before use. It is important to choose safety shoes of appropriate strength based on the intensity of the work.

(3) Anti-static Shoes and Conductive Shoes

Anti-static shoes are used to prevent accidents caused by static electricity buildup on the human body and to avoid accidental electric shocks from 220V power-frequency capacitive equipment. Conductive shoes are intended for flammable or explosive environments where static electricity poses an even greater hazard. Many of these shoes integrate anti-static or conductive soles with safety shoe or rubber shoe structures, and use no metal components throughout to reduce the risk of friction-induced ignition. Resistance testing must be performed when the shoes are first put into use, followed by regular testing to ensure the maximum resistance value remains within the allowable range.

(4) Steelmaking Shoes and Shoe Covers

Also called foundry shoes, these are mainly used to protect feet from burns, scalds, and punctures. They feature pressure resistance and non-flammability, with uppers made of oil-tanned cowhide or canvas trimmed with leather, and soles made of tire rubber lined with cowhide leather. To prevent scalding from splashing molten metal, they are usually high-top and easy to remove. Shoe covers, typically made of canvas, asbestos, or aluminum film, can also be used to cover the shoe openings and trouser legs for extra protection.

(5) Cold-proof Shoes

Suitable for work in frigid and low-temperature environments, these include cotton-padded shoes, fur boots, felt boots, etc., and provide excellent thermal insulation.

(6) Rubber Boots

Classified by function into acid-alkali resistant boots, waterproof boots, oil-resistant shoes, etc.

Acid-alkali resistant boots: Used in workplaces with acid, alkali, or other corrosive liquids on the ground, made of acid-alkali resistant rubber. One-piece acid-alkali resistant trousers and boots are also available.

Waterproof boots: Used for work with standing water or splashing water, mainly made of rubber, including miner's waterproof boots, aquaculture-specific boots, rice transplanting boots, etc.

Oil-resistant shoes: Used in workplaces with oil-contaminated ground, made of rubber or polyethylene plastic, available in both shoe and boot styles.
