Tingley 28259 Flite Safety Toe Knee Boot with Safety-Loc Outsole

The Tingley 28259 Flite Safety Toe Knee Boot is a lightweight, chemical-resistant knee boot designed for demanding industrial environments where both protection and mobility matter. Built with Aerex 1.5.5, a proprietary microcellular polymer, these boots are reported to be more than 40% lighter than typical steel-toe PVC or rubber knee boots, helping reduce fatigue over long wear. The upper is a gray, 15-inch-height design with a composite safety toe that meets ASTM F2413 M/I/C EH standards, and the orange Safety-Loc outsole provides slip resistance across dry, wet, and contaminated surfaces. The seamless upper is 100% liquid proof, which helps keep feet dry in damp or splash-prone settings, and the insole is replaceable for extended wear life. An added benefit of Aerex 1.5.5 is the material’s insulation properties, helping feet stay warmer in cold conditions and cooler when temperatures rise, while still maintaining a lightweight profile.

This boot is intended for use in food processing contexts (including dairy, meat, vegetables, and refrigerated or frozen environments), as well as farm, chemical, and petrochemical applications where chemical resistance and durable waterproof performance are important. It features Calf-Relief Topline for easier on/off and roomier calf space, and a beveled heel to promote better alignment and reduce strain during foot movement. While the outsole offers electrical-hazard protection, users should note that the EH characteristics can deteriorate in wet environments or with heavy wear on the soles and heels. The product supports environments where a non-metallic toe and a liquid-proof surface are advantageous, and it is supplied in a case quantity of six pairs per package, with each unit configured as a pair.

For practical considerations, the boot is designed to be non-lined and insulated, which aligns with its thermally-insulative claim but may affect certain comfort preferences. The design also emphasizes compatibility with replaceable insoles and a slip-resistant nitrile rubber outsole, making it suitable for slippery or oily work zones and for workers who need a sturdy, all-weather boot option. Accessory downloads, including the spec sheet, are available to help verify fit, construction, and compliance details.
