I had two pair of 1461s, one in black, one in brown. They were my "I've been told not to spook the normies" work shoes, suitable for meetings and site visits. Two years. Two years I got out of those things. Split between the two of them. Work boots should last forever, and if you're going to wear work boots you can do better than Docs.
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.
