Molded Heel Counter
A rugged heel counter is individually molded to fit each size perfectly.

LENZI® Puncture Protection
This high performance penetration protection is made from multiple layers of HT ceramic material like ballistic armor for your feet. Far more flexible than a steel plate and doesn't transmit heat or cold. Meets NFPA standards for safety.

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

Nitrile Rubber Contoured Cup Outsole
Molded outsole wraps onto the upper for athletic shoe perfomance. Flame, abrasion, oil, acid, and slip resistant compound engineered for high-traction and durability. Siping lines cut into flat areas open 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.

3D Molded Shin Guard
Molded and padded shin guard provides extra protection when you are working on a ladder.

Reinforced Pull-Straps
Pull-straps are internally reinforced for added strength and to keep them upright. Straps are securely box and cross stitched to keep them on for good.

Quick Zip Closure
The 10" Zipper/Speed Lace model combines the advantages of a lace-up for a custom fit and the convenience of a zipper.

FIRESTORM™ Leather
Heavyweight flame-resistant and waterproof leather for durable performance. Leather has added reflective material at the heel for nighttime visiblity. Specially softened tumbled leather in high flex areas to move with you.

CROSSTECH® Footwear Fabric
A full-height bootie made from a package of Cambrelle®, 300g insulation, and CROSSTECH® mositure barrier provides performance unmatched by any other waterproof, breathable barrier.

3M SCOTCHLITE™ Reflective Material
Flame-resistant fluorescent and reflective material for added visibility.

Custom Fit System
A second removable footbed is provided with every pair for a custom fit. Use this thicker footbed for a snugger fit or when wearing with lighter socks.

3D Contoured Lasting Board
Boot uppers are lasted to a molded and contoured dual-density lasting board with a built-in flex zone in the forefoot and a torsionally stable heel. Works together with the 3D molded footbed to conform to the shape of your foot.

Cement Construction
Contoured outsoldes are cement-bonded to the bottom and sides of the upper using a 2-part cross-linking adhesive that forms a bond stronger than the materials it attaches. Without stiff welts and ribbed mid-soles, this attachment process is far more flexible.

3D Molded Footbed
Dual-density removable footbed is contoured to cradle and cushion the bottom of your foot and to provide arch support. Built-in polymer strike pades provide extra impact protection. Moisture wicking and anti-microbial fabric top layer.

Nitrile Rubber Toe Bumper
Made from the same rugged coupound as the outsole for abrasion resistance when crawling. Cemented and 2-needle stitched to the vamp.

Composite Safety Toe Cap
Lighter than steel and meeting NFPA standards for safety. Doesn't transmit heat or cold.
