The boots normally allow walking on hot surfaces up to 300C and are oil, petrol, water, acid and alkali resistant. They resist the build-up and conductance of static electricity and are of most benefit when walking on synthetic carpets or near electrical machinery. Dual density polyurethane/rubber soles provide wearers with extra comfort. The sole features a nitrile rubber outsole, resistant to heat to 300 and a low density polyurethane interlayer, for increased comfort and shock absorption. The boots are water penetration and absorption resistant and help to keep the feet dry in wet conditions. S3 classified. Manufactured to EN ISO 20345:2011.
