Gotta step in here before this thread turns into the usual barrage of attrocious footwear advice when 'Best Boots' are mentioned...
There are NO best boots. My Zamberlan Trail Lite GTX are the best boots FOR ME. But unless you've got a narrow foot, they're going to be uncomfortable.
If you are really serious about outdoor footwear, find a dealer that follows the "Phil Oren Fitsystem" (
www.fitsystembyphiloren.com/ ). This bootfitting method ensures that you are fitted with the ideal boot for both the shape of
your foot and the type of terrain you would generally use it in.
An experienced bootfitter with the Phil Oren qualification will measure your foot with you both sitting and standing, will assess the condition of your feet for bunions, callousing, bone spurs and other minor foot problems and advise you towards a combination of sock, footbed (insole) and boot that is perfect for you. They should also be able to modify the boots by stretching (for bunions, bone spurs, etc) if neccessary.
Of course, if y'all arn't serious about the single most vital part of your clothing setup, just by a pair of Brasher Hillmasters or a pair of Berghaus Explorer (i've seen 'no-brand' hiking boots for £15-£25 that in my opinion are better made and better designed than either of these boots).
If you use your boots for dogwalking, don't expect them to last more than a year - there is no activity that kills boots quicker than dogwalking. Do the maths: 2-3 miles a day is the dogwalkers average, 350+ days a year = over 1000 miles. More than even the most Rampant Rambler is likely to manage. Best advice I can give here is buy a cheap pair for dogwalking and a quality pair for bushcraft - shouldn't be a problem if cost isn't an issue.
Sorry if this advice seems a little abrupt, but this was my job, A Phil Oren Fitsystem Bootfitter, for 18 months with one of the country's premier Outdoor Footwear retailers (as regarded by the industry). So I do know what i'm talking about here, and when i've looked at 'Boot' queries on BCUK in the past i've seen advice that ranged from 'bad' through 'stupid' right out the other side, all the way to downright dangerous.
