So, if a pair of work boots meets any of those descriptions...it's absolutely bad to wear them all day. You aren't going to be comfortable, and wearing them long-term can actually lead to injuries.
And it should also be said that this applies to ANY footwear - not just work boots!
It Also Depends On What You Mean By "Work Boots"
A lot of different makes and models of footwear could be said to be "work boots." Any boot that you can wear...for work...are work boots; the question is what work you're doing in them.
Look at the myriad of heritage boots on the market. These are older styles of practical footwear, in many cases 6-inch or ankle boots, with a relatively low-profile sole and modest heel block. Examples abound, and some for a hefty price tag...though some are definitely worth it!
Are those "work boots"? Not as the term is commonly understood, no, but those are exactly the design of work boots and shoes that thousands of loggers, miners, mechanics, factory workers, tradesmen and - yes - even our soldiers wore for much of the 20th century.
So they are work boots, it's just that many people mentioned above - loggers, miners, mechanics, factory workers and tradesmen - wear a different style of boot today...for good reason of course!
There are also plenty of work boots that are also worn casually. From lighter duty boots to lain and moccasin-toe wedge sole boots are just as popular for everyday casual wear as they are on job sites. The low heel profile and flat sole are supportive, comfortable and feel almost sneaker-like on the foot.
Are any of those bad to wear every day? So long as they are properly constructed and taken care of, not at all.
However, would a pair of 10-inch logger boots be comfortable to wear in an office everyday? Once broken in, they'd be plenty comfortable but your feet would ROAST under a desk, and that wouldn't be pleasant.
In that light, is it bad to wear work boots every day?
Of COURSE not. Ankle boots are the perfect medium between dress shoe appearance and work boot support, which a lot of people prefer. Arguably, they're the perfect do-it-all footwear.
If you purchase a pair that's sized correctly for you, is made correctly, and gives you the support and comfort you need...how could that be bad?
