The PRO S4 SRC work wellingtons, size 46, 82-900-46 by NEO, are made in S4 SRC class with PVC and polyamide knitted lining. The non-slip sole with a shock-absorbing system provides an increased level of safety when using the footwear. In addition, the built-in heel and composite toecap protect the foot from mechanical injury. The sole is also resistant to abrasion, oils, petrol, and other organic solvents. The anti-electrostatic properties and slip resistance on both a ceramic base coated with sodium lauryl sulfate solution and on a steel base coated with glycerol contribute to a higher degree of protection against mishaps. The wellingtons are coated with the antibacterial Ultra Fresh. This model is EN20345 compliant.
