the government can be very finicky with H&S and you may find that they had to Trial those boots. I have to wear boots at work admittedly they were Issued to me, but I'm not allowed to wear my own because the Issue boots were trialled and shown to be up to health and safety standards for my line of work. and If I was to have an accident at work wearing my own boots I will not be covered by the "companies" insurance Policy. and there are varying levels of foot protective boots well if you want to go to prison its upto you but Id rather have on my criminal record "80hrs CS" instead of "Banged up"
