What does FI indicate on safety footwear labeling?

• A. Female and the impact resistance rating
• B. Fire index
• C. Frost resistance
• D. Friction index

Answer: (A)

FI on safety footwear labeling signals two things: F stands for female fit, and I stands for impact resistance. The female designation means the shoe is designed with a shape and size intended for women, often with a different last and fit. The impact resistance rating shows the toe cap is tested to withstand a specified energy from a falling object (often noted as I followed by a joule value, like I/75). Together, this marking communicates both who the boot is designed for and its protective capability. This isn’t about fire index, frost resistance, or friction index, which use different markings or criteria.
