Notes:
There are four tests that are mandatory for testing and each boot will have a rating for each of these sections. So if the inner label reads: 2 2 2 2 - then the boot is an overall level 2 rating, which is the highest level of protection. If the label reads 1 2 2 2 - then the overall rating will be a level 1 but the only reason, will be due to the height of the boot. These are the tests these ratings refer to:
- Height of Upper
- Impact abrasion resistance of the upper
- Impact cut resistance of the upper
- Transverse rigidity of the whole footwear
