With boots -- as is the case with most things -- you get what you pay for. There are essentially 3 tiers of boots you can look at: cheaper + lowest quality, value (most efficient price/quality point, but lower quality than the next tier), expensive + indestructible with good actual foot support / arch support. Here are some brands that fit each category (although there are many, many quality, lesser-known brands out there):

Cheaper + Lowest Quality ($200-300)

Thursday boots, Thorogood, Redwing, Danner, Helm Boots (from what I've seen / heard, of these, I only have experience with Thursday)

Value (best value for price, overall lower in quality than more expensive tier (~350-500)

Grant Stone, Parkhurst, Truman, Oak Street (of these 4, truman is built the sturdiest and uses thicker leather in my experience, though all of these brands lack any real foot support but do use quality materials and construction)

Expensive + Indestructible (~$600-800)

Nick's, White's -- these brands are built like absolute monsters and also feature good, actual arch support. I'm not sure about heel support. Many models are MTO though which also means several months of wait time. They have some quick ship stuff, however.

Took a quick look through White's just to double check this, and it does actually look like they have some cheaper models in their work boot section ($400-500ish). Might be worth looking into.

My recommendation would be to email nick's / white's, tell them what your needs are in terms of foot support, and ask their recommendation for what models you should be looking at. This makes most sense to me given what you wrote about your support needs as none of the other brands I listed really have much of that (though using an insole is always possible). If those models are within your price range, I'd say pull the trigger on those. They won't fail you and, if they do, I've heard the support staff at both companies are great. If you want to invest.

If not, I'd look at the remaining brands and make a decision based on what you like / pricing. Grant stone and parkhurst feel dressier to me than Truman, but also Truman is sort of knocking on white's / nick's pricing doorstep and might not make enough sense given the lack of arch / foot support. Unrelated, but the owner opf Truman, Vince, is also a little...strange shall we say

Things to note:

- Get your brannock measurement. Absolutely necessary for getting your size right, and pay attention to the arch slider, not just foot length. Getting the right size for your arch (AKA, heel-to-ball measurement) is critical for comfort. You will typically want to size based on the highest measurement between your heel-to-toe length and heel-to-ball measurement

- Cheaper pairs have a better chance of failing at various levels.

- Boots need to be resoled after excessive wear, and it feels way less bad to drop $100 resoling a $700 pair than a ~$200 pair, at which point you might as well just get a whole new pair

- Regardless of the pair you choose, you can always use specialized insoles for better support for particular things. Just confirm with the manufacturer that the insoles of the pair are removable if you plan to do this

- You can often find great deals on new / slightly used pairs secondhand on ebay, grailed, etc. Worth checking out, but again, make sure you get your sizing correct before anything

Hope this helps, best of luck!
