Work shoes are the shoes used by workers in order to avoid accidents at work. As a key feature they have the finger guard. Of course, the protective midsole and the non-slip outsole also play an important role. Based on the security they provide, they are given the appropriate degree of protection, according to the European specification EN ISO 20345:2011. The table below gives a detailed overview of the feature codes as well as the required (minimum) safety performance.
SB: Basic safety shoe with metal or synthetic polymer finger guard
S1: SB + closed in the heel area + anti-static properties + anti-vibration heel
S1P: S1 + anti-puncture midsole
S2: S1 + resistance to water penetration and absorption ( waterproofing )
S3: S2 + anti-puncture midsole
P: Resistance to perforation of the sole ≥ 1100 Ν
E: Absorption energy of the heel ≥ 20 J
A: Resistive bounce between 0.1 and 1000 MΩ
C: Conductive shoe < 0,1 MΩ
WRU: Resistance to penetration and water absorption (upper part) ≥ 60 min.
WR: Waterproof shoe ≤ 3 cm2
Cl: Cold insulation Test at -20 oC
HI: Heat Insulation Test at 150 oC
HRO: Outer sole with resistance to contact heat Test at 300 oC
I: Electrically insulated shoe of classes 0 and 00
M: Metatarsal finger protection (only for EN ISO 20345) ≤ 40 mm (No 41/42)
AN: Ankle protection ≤ 20 kN
CR: Cut resistance ≥ 2,5
