SRC Slip Resistance Explained
SRC is the highest slip resistance rating, combining SRA (ceramic tile with detergent) and SRB (steel with glycerol) tests. Safety shoes with SRC rating provide excellent grip on both wet and oily surfaces.
TIPFor construction sites and wet environments, always choose S3 rated safety shoes with SRC slip resistance.
