Blackrock Lincoln S3 Fully Waterproof Non Metallic Safety Work Boot with Metatarsal Protection,Leather Metal Free Composite Toe Cap & Protective Midsole,Ankle Support

Poron XRD Metatarsal Protection: an ultra-high-tech material that hardens within a tiny fraction of a second after impact, dissipates energy from the metatarsal bone and then immediately relaxes to protect the bone that most commonly breaks when objects fall on the foot. WATERPROOF LEATHER UPPER: Thanks to a fully waterproof membrane carefully sewn into the upper, the boot can be submerged to just below the ankle, keeping your feet dry even during prolonged work in wet environments. Non-metallic composite toe cap protects against impact from falling objects and pressure. It offers protection of 200 joules - equivalent to a drop of 20 kg from a height of 1 m or a weight of 1.5 tonnes that loads on the toe area. Composite midsole: a thin but sturdy plate made of lightweight, non-metallic material that extends the entire length of the sole and protects against objects that penetrate the foot from below and pierce it, such as such as nails, tacks, broken glass, etc., which could otherwise cause serious injury. Ultra durable PU/rubber sole that can withstand temperatures up to 300 C and is resistant to fuel oil, so it won't wear out, discolor or retain grease that would otherwise lead to slips and tripping. Other features: durable abrasion cap that provides more protection and abrasion resistance in the toe area; Cushioned EaziStep comfort sole that cushions every step; Energy-absorbing heel that reduces foot fatigue; Anti-static sole that minimises the build-up of electrostatic charges; Non-slip sole.
