I use military issue boots (or ex mil) from army surplus supply shops.
last pair lasted over 10 years...
having said that all 3 of mine gave up the ghost last year so bought some new style whilst comfy as feck & Gortex they have a side panel that are bit breezy in this weather!
my mate gave me a pair of Daytona M Star GTX boots & they are great & comfy enough to walk about in!
