The Kosto PBK060 Airmet boots are 8-inch tall safety footwear engineered for demanding industrial settings that require metatarsal protection, heat resistance, and waterproofing. Lightweight and metal-free, these dielectric boots include an internal Poron XRD® Metguard that remains flexible under normal conditions but instantly hardens upon impact. Combined with a 200g Thinsulate™ lining, flame-retardant stitching, and a PU/rubber outsole resistant to 300°C, they provide comfort and reliability across high-risk environments.
Key Features
Internal Poron XRD® Metguard hardens on impact for metatarsal protection
Full grain leather upper resists wear and moisture
Dielectric, metal-free construction suitable for electrical environments
Composite toe and puncture-resistant plate meet CSA and ASTM safety standards
PU/rubber outsole heat-resistant up to 300°C for one minute
200g Thinsulate™ insulation for cold weather comfort
Cambrelle® lining enhances moisture wicking and odor resistance
Padded collar and memory foam insole increase long-wear comfort
Wear-resistant bumper toe and flame-retardant stitching extend durability
Intended Use
The PBK060 boots are tailored for workers exposed to extreme heat, impact hazards, and wet or electrically sensitive environments. Their dielectric design and internal metguard make them ideal for utility workers, welders, foundry laborers, and construction crews operating around sparks, splashes, or energized equipment.
