Over recent years rigger boots have become popular because they are easy to put on and are a cross between lace up boots and wellingtons. However some companies have found that wearers of rigger boots are much more likely to suffer twisted or sprained ankle injuries. They think this is because rigger boots are a looser fit and the wearer is less able to prevent the foot from twisting to the side on uneven ground. This is the reason that some contractors will not allow them on site. This is an acceptable argument and you need to understand and comply with this rule.
Lace up boots are not normally suitable for licensed asbestos work within an enclosure.
