The Tingley 27251 Flite Safety Toe Knee Boot is a knee-high work boot designed to provide protective footwear for environments where chemical exposure and cold or warm conditions may be present. It features a composite safety toe and a cleated, slip-resistant nitrile rubber outsole, paired with a 15-inch tall black upper and a seamless, 100% liquid-proof upper for reliable containment against liquids and contaminants. The boot is constructed with Aerex 1.5.5, a proprietary microcellular polymer described as chemical-resistant and thermally insulating, which contributes to a lighter overall boot weight while maintaining insulation and flexibility. A notable feature is the Calf-Relief Topline for easier on-off and roomier calf space, along with a beveled heel intended to reduce back and leg strain during long shifts. The outsole includes tread wear indicators to help track remaining sole life, and the boot’s composite toe meets ASTM F2413 standards and is designed to avoid triggering metal detectors. The product is advertised as having resistance to fats, oils, hydrocarbons, certain acids, and caustics, making it suitable for use in food processing, agriculture, chemical, and petrochemical applications, with additional note on viral penetration resistance per ASTM F1671.
In practice, this boot is intended for adult unisex use and is water resistant and waterproof, with replaceable insoles and the option for ongoing maintenance of a dry, protected foot environment through the boot’s sealed construction. The case quantity is six pairs per package, and the outside vamp material is Aerex 1.5.5, contributing to the overall performance characteristics described by the manufacturer. As with any chemical-resistant footwear, users should consider environmental moisture and wear conditions, as the electric hazard features may deteriorate in wet environments or with excessive wear on the soles and heels.
