It doesn't stop the ladder from ever sliding ever under any circumstance. It's a help to stabilise the ladder and nothing more.
If you go up the ladder further up than 90 degrees in a straight line vertically past the 'foot the ladder' the forces are still trying to push the ladder away from the wall. It's just those forces are not as great as if you didn't have 'foot the ladder'.
In some ways the advertising of 'foot the ladder' is misleading as it's not the same as footing the ladder.
The Rojak ladder device relies on friction and nothing more.
If any think that any ladder safety device means that it's ok to stretch the boundaries of using a ladder safely, or takes risks they wouldn't have otherwise taken, they could be in for a painfull shock.
These devices add further safety to what should already be a safe way to use a ladder. They do not replace safe usage in anyway, shape or form. They are for added safety and not in replace of.
