I wore docs in the shop back in the mid '90s. Standing on concrete all day is a real test of comfort. Back then Docs were still made in the UK, and mine had leather pull straps, were fully lined with padded collars, and had leather heel counters inside the boots, where the back of your heel rubs the lining.
They were good boots, comfortable and lasted. After two pairs of them, the company changed - the leather pull straps became fabric (and tore out the first time you actually used them), the lining became partial, the leather heel counters became cardboard.... and the boots got more expensive. They didn't last like they used to under daily use, either. You could get all kinds of colors, finishes and patterns, though!
I switched to Red Wings ( black 607s, if you care). Union made in the USA, leather padded collar and leather heel counter, partially lined, a real insole. A quality, comfortable work boot that lasts - I'm on my third set in 10 years, and I wear them every day.
Not waterproof, though (and they do offer waterproof boots). I got mine from Dave's in New York last time I was on the east coast since they had the best price:

Red Wing also has a cheaper imported Worx line. Never used them (and I never will), so I can't say if they are any good.
