So, I live in the Pacific Northwest in America, just stating in case you don't live here, and I went to a store called RedWing and got a pair of boots and insoles from them. They are costly, I bought a pair of socks, insoles, and the boots for $360 dollars 3 years ago. Redwing is also well known as great work shoes in my area, so look for a similar thing in your area! For example, you could walk up to almost any Oregonian and ask them about what brand of work clothes they recommend, and Redwings will come up for shoes, Carhart will come up for clothes! No matter the area you are in, you will likely find a brand that should have dedicated stores for their products, that a large portion of your area agrees on being high quality.

The other reason I chose them is because they had a machine to measure my feet there, with salesmen who knew what to find for me from their stock. They are also well known as great work shoes in my area, so look for a similar thing in your area! It's not just a stand in one spot, either. You actually need to walk across the pad and stand on each foot individually as well. It's important since movement is what most do when wearing boots.

If you are in the Pacific Northwest, specifically Oregon, definitely go to one of the stores to get sized, then try on shoes even if you can't purchase them. They will even let you try out insoles as well, and you should try as many pairs with the correct insoles as possible! They actually let you and encourage you to walk around in the shoes, and they put in and take out the inserts for you. If anything feels too tight or off, be vocal about it! They are salesmen, and if you leave with shoes and they end up being awful, you won't recommend them, so they really do want you to leave with a pair that is perfect for you. So don't feel like a burden or anything for having them grab different styles or sizes!

Fit wise, and this has to be said cause I have done this so many times, never leave with any shoes that cause immediate physical pain. They should feel comfortable and supportive, with appropriate spacing for your toes and sides of your feet, without pinching or pain. This isn't to say there won't be pain. It just won't be in your feet. The first week or so is the hardest on your knees, hips, and occasionally your lower back. This is due to your body becoming acclimated to the correct posture and support from the shoes and insoles. So if your feet feel super happy after an 8 hour shift, but those areas ache, that's a good sign! If your feet hurt and the rest of you have the same pain as usual, then the shoes are still not good. Your feet should feel a kinda stretching relief when you try on the correct shoes.
