I'm late to the party, and I think I've said this before, but if you need disposable work boots, you could do a lot worse than Thorogoods.
I've had mine for two and a half years. The soles are shot. I could resole them, but I've worn the leather through on the toes from kicking boxes. They look like hell, but I can still probably get another year out of them. They are comfy. Union made. And way cheaper than buying $60 shoes every five months.
If you're poor, watch the spring/fall Amazon fashion sales. For whatever reason, they tend to get included in those.
