About These Icons


TECTUFF™ PU coated leathers use a proprietary process and chemistry which delivers extreme durability. The polyurethane formula is securely bonded through heat and pressure to the leather substrate. The resulting finish is the most durable in the industry and is impervious to dirt, oil, and stain penetration.


20% lighter than previous generations, Kryptoe® technology incorporates specially woven fibres with highly impact-resistant resins. The result is a globally certified, lightweight, low-profile composite toe.

XRD® Metguard

New breakthrough flexible materials with XRD® technology. Designed to stay flexible in motion, but turn into an ultra-dense protective barrier upon impact.


CLEANFEET® odor control treatment is a game-changer in the footwear universe. This patented technology doesn’t just help odor - it actually works to prevent odor before it starts. CLEANFEET® stops odor dead in its tracks. CLEANFEET® is a natural and safe method of controlling odor, guaranteed for the life of your workboots.
