Each safety style states its EN ISO rating
HSE figures put slips and trips as the most common cause of non-fatal workplace injury in Great Britain, and the floor you stand on decides which sole you need. Every style here states a slip-resistance marking in its listing: SRC under the 2011 edition of EN ISO 20345, or SR under the 2022 edition. We list 708 of them ready to order.
SRA was tested on ceramic tile with a detergent solution, SRB on steel with glycerine. SRC means the sole passed both.
The 2022 edition made the ceramic tile test part of every S rating and added SR for a harder test on ceramic with glycerine.
Wet and greasy floors are where slip resistance earns its keep. See the food industry collection for hygiene-area styles.

Slip resistance is tested on the sole, on set surfaces with set contaminants, so a marking tells you what a sole passed in the lab rather than promising grip on every floor. Under EN ISO 20345:2011 the codes were SRA, SRB and SRC, with SRC the combination of both tests. The 2022 edition folded the ceramic tile test into every safety rating and introduced SR as the additional, harder test. You will see both on the market because footwear certified to either edition is still sold. Each product page here lists the style's own markings.
Choose the base rating first, then the conditions. Working in kitchens or food production, see our food industry safety shoes. On ladders and scaffold all day, the LG marking matters too: see our ladder grip safety boots. For what S1P, S3 and S7 add, see the safety boot ratings guide.
