Blackrock 8" Metshield Composite ESD Waterproof Work Boots, Cold Insulation, Metatarsal S7L Protection, Ladder Grip, Heat-Resistant Sole, Mens Womens, Metal-Free Heavy-Duty Safety Boot, Size 4

METATARSAL PROTECTION - an ultra-high tech material that hardens within a tiny fraction of a second of impact, dissipates the energy away from your metatarsal then instantly relaxes again, protecting the bone most commonly broken when objects are dropped onto the foot

WATERPROOF LEATHER UPPER: Thanks to a fully waterproof membrane that is carefully sewn into the upper, the boot can be submerged to a point just below the ankle, ensuring your feet stay dry when working in wet conditions for extended periods

COMPOSITE TOE CAP: Woven fibre, non-metallic, composite, lightweight material protects against impact from falling objects and against compression, giving 200 Joules of protection - equivalent to dropping 20kg from a height of 1m or a weight of 1.5 tonnes resting on the toe area

COMPOSITE MIDSOLE: A thin yet strong plate of lightweight, non-metallic material that runs the length of the sole and protects against objects penetrating from below and piercing your foot, such as nails, tacks, glass shards and more, that could otherwise cause a potentially serious injury

HEAVY DUTY HRO SOLE UNIT: PU/rubber sole that can withstand temperatures up to 300°C and is resistant to fuel oil, so it won't degrade, stain or retain grease that would otherwise cause slips and trips
