STRUCTURAL 12”

This is the boot for those who prefer the adjustable fit of a lace up boot for Structural Fire Fighting. Built with our remarkably flexible athletic footwear construction, STRUCTURAL 12” shares the cushioned and contoured foundation and superior slip resistance of our pull on boot styles.

NFPA 1971 (Structural Fire Fighting)
NFPA 1992 (Liquid Splash)
MADE IN THE U.S.A.

Flame-Resistant, Water-Resistant Heavy Duty Leather
Specially softened tumbled leather in high-flex areas to move with you.

GORE® CROSSTECH® Footwear Fabric
A full-height bootie liner made from a package of Omaha lining fabric, 300g insulation, and CROSSTECH® moisture barrier provides protection unmatched by any other waterproof, breathable barrier.

QuickZip Closure
The advantages of a lace up for a custom fit and the convenience of a zipper.

Composite Heel Counter
Individually molded to fit each size perfectly.

Composite Safety Toe Cap
Lighter than steel, doesn’t transmit heat or cold, and exceeds NFPA standards for safety.

VIBRAM® Toe Bumper
Made from the same rugged compound as the outsole for abrasion resistance when crawling.

3D Molded Removable Footbeds
Contoured to cradle and cushion the bottom of your foot and to provide arch support. Moisture-wicking and anti-microbial fabric top layer. A second, thicker removable footbed is provided for a snugger fit or when wearing lighter socks.

3D Composite Lasting Board
Molded, contoured, and lasted to boot uppers with a built-in flex zone in the forefoot and a torsionally stable heel. Works together with the footbed to conform to the shape of your foot.

Composite Shank
Lighter than steel, doesn’t transmit heat or cold, springs back to shape better.

Composite Puncture Protection
Far more flexible than a steel plate and doesn’t transmit heat or cold. Exceeds NFPA standards.

VIBRAM® Contoured Cup Outsole
Molded outsole wraps onto the leather upper for athletic shoe performance. Flame, abrasion, oil, acid and slip-resistant compound engineered for high traction and durability even during prolonged exposure to extremes of heat and cold.

Athletic Footwear Construction
2-part cross-linking adhesive bonds outsoles to the upper. Without stiff welts and ribbed mid-soles, this attachment process is far more flexible.

Slip-Resistant Tread
Siping – thin slits cut into flat areas across the sole – opens up when flexed to provide additional traction on water and ice. Self-cleaning lugs and omni-direction tread pattern designed for superior performance in all terrains and when working on ladders.

Extended Size Range
Men's: Full Sizes 5-18 and Half Sizes 5½-15½ in Narrow, Medium, Wide, and X-Wide widths.
Women's: Full Sizes 5-12 and Half Sizes 5½-11½ in Narrow, Medium, Wide, and X-Wide widths.
