I've been sporting Thorogoods for the past 5 years or so. Damn good boots.
I currently own 3 pairs of thorogood boots now, they have the perfect balance of quality comfortably and longevity for the money.
The biggest selling point for me is the machined brass speed hooks, my Justin conductor's ( discontinued in black) use the bent type that are always getting pinched on me .
The quality on Justin's isn't as good anyways, not bad but not as good.
I'm technically supposed to have all black boots at work, but I decided to say screw that.
These are black enough, and I'm not compromising on footwear ( and my beliefs) for anybody just to meet a technicality.
If my boss says something ( he won't) I'll tell him this is what was available in my size that meets safety requirements , basically meets the dress code requirement, and meets my personal requirements.
I'm not buying imported crap, must be leather, no cemented construction, and I've gotta have a traditional boot not that anything else tends to meet my requirements anyways.
I may dye the stitching black, but I'm not going to bother with the soles.
