The Corona safety trainer features a leather upper with both steel toe cap and midsole protection. Its hardwearing, dual density PU sole is shock absorbent, anti-slip, anti-static and fuel oil resistant. This footwear is designed with a steel toe cap that protects against impact from falling objects and against compression, giving 200 Joules of protection. A thin yet strong steel plate 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. The dual density PU/PU sole is resistant to fuel oil, so it won't degrade, stain, or retain grease that would otherwise cause slips and trips. It also features an energy-absorbing heel that reduces foot fatigue and an anti-static sole that minimises the build-up of electrostatic charges. The sole is slip-resistant. Blackrock safety footwear is designed with a wide fitting to allow for thick boot socks to be worn. Safety rating S1-P SRC.
