Dangerous: Crappy, deteriorating soles
Produce (or at least have produced) outright dangerous safety shoes with deteriorating soles. Customer service ignores all e-mails etc. - so IF the company is still alive, I recommend avoiding them at all cost! And IF you should be so unlucky to own some of their shoes, be sure to check the integrity of the soles regularly... Because some of them WILL try to kill you!
