Protec 6"

They're incredible shoes and do their job very well, however the laces are a little short and they're "non-slip" and "anti-oil" qualities don't work incredibly well, unless anti-oil means that oil doesn't stain, in which case that facet works perfectly, however I am still more than capable of slipping, possibly even more so than my prior boots, although this is because I walk on surfaces that consistently get coated in oil and become incredibly slippery. All in all, very good boots though.
