Our wear ratings are for guidelines only and illustrated with foot symbol. 5 ‘yellow dots’ signal the highest wear rating, meaning these products are suitable for heavy-duty use. ‘3’ is for moderate and 1 ‘yellow dot’ is for lightweight use only. Each environment is different and some locations may be more punishing than others. Our wear ratings are there to give you some guidance on each product’s durability.
