Boots are in great functional shape, lots of life left in them. I used them in a food production plant, but I no longer work there and have decided to sell them. These can be worn in a work setting, but would also be great boots to use in wet, sloshy, muddy conditions, because they are insulated and waterproof. Entire boot is in one piece, there is no separate insole, it's built in, which I think adds to the durability and long life the boots have to offer. The only real flaw is that the rubber on the bottom, inside right side of the sole is pretty scuffed, but it doesn't affect the performance of the boot at all and isn't noticeable while being worn, or by observing because it's minimal and out of view, unless looked at up close.

Key Aspects of ASTM F2413-18

• Purpose: Sets minimum design, performance, and testing criteria for safety footwear to prevent injuries from hazards like falling objects, sharp objects, and electrical shock.

• Protective Features: Addresses various hazards, including:

• Impact Resistance (I): Protection against falling objects (e.g., I/75 means protection against 75 ft-lbs of impact).

• Compression Resistance (C): Protection against crushing (e.g., C/75 means protection against 2500 lbs).

• Metatarsal Protection (Mt): Shields the top of the foot.

• Electrical Hazard (EH): Resistance to open circuits (e.g., 18,000V).

• Static Dissipative (SD): Reduces static electricity buildup.

• Puncture Resistance (PR): Protects soles from sharp objects.

• Labeling: Footwear compliant with F2413-18 has specific markings indicating its protective features (e.g., "ASTM F2413-18", "M I/75 C/75", or EH, SD).

• Testing: Footwear undergoes controlled laboratory tests for impact, compression, and other hazards to meet standard requirements. 

Key Aspects of ASTM F3445-21:

• Purpose: To reduce slip-and-fall injuries in workplaces by standardizing slip resistance in safety footwear.

• Scope: Covers minimum slip resistance requirements for protective (safety) footwear, going beyond basic traction to mimic real-world conditions.

• Testing: Uses the ASTM F2913 Test Method to measure the Coefficient of Friction (COF) on various surfaces, providing a standardized benchmark.

• Labeling: Allows manufacturers to label footwear as "Slip Resistant (ASTM F3445)" when it meets these criteria, providing clarity for buyers.

• Coverage: Includes performance on dry, wet, and oily/wet surfaces, addressing diverse workplace hazards.
