I have bad feet, and really need to buy some proper walking shoes/boots which can be done up nice and tight to support my feet better

Can anyone tell me exactly what they wear, and how much out of 10 you would give them? What is good/bad in a walking boot?

Budget is about £100. Most walking is across fields which are obviously a bit uneven and hard through the summer. No real hills around here.

I know people have asked this before, but I'm hoping for more recent recommendations (the boots I originally wanted have been altered and I like the new ones less).

Thanks
