several recomendations...
i've been wearing the Lowa Mountain GTX for about 5 years, they are/were my, err... mountain boot of choice, i'd wear them anywhere it was rocky (snowdonia, highlands etc.. or particularly wet - mid-wales, north pennines... they have been replaced by the Haix Cold Wet Weather boot, the haix has, i think, a slightly more felexible sole unit than the Lowa, but they have passed with flying colours the 'Cold, Wet Weather' test - they did a 4 month, straight out of the box, Falklands winter tour with most of the time spent on the mountains and and in the bogs of West Falkland.
Alt-berg defender - i wear them most days and they are very comfortable, they are pretty waterproof, and when it does get through they dry out quickly. i'll wear them in preference to the Lowa or Haix above if its dry(ish) or warm(ish), and the sole is stiff enough, and the boot supportive enough to wear them for a week in the mountains with a decent sized rucksack.
Meindl Borneo are my 'go to' walking boots for summer days in the mountains, and pretty much any lowland walk in any weather. lighter, and cooler than the high leg boots i've mentioned above, they are the boots i'd choose to wear if i was walking the Hadrians wall path, or Offas Dyke..
Grisport Ranger boots are a pair i bought for 'posh' shooting days when turning up in my service boots got a slightly sniffy look from some quarters. they are wonderfully comfortable and supportive and i can happily wear them all day - they also look amazing. however, the sole unit is not, imv, built for rocky mountain walks - fantastic on farmland and forestry, and great for moorland, but (imv) the sole unit is too soft for the endless rock gardens of the ridges and corries of the central and western highlands.
not one of these boots has failed me in terms of its materials or construction - the note about the Grisport boot should not be taken as a criticism, its just what its built for - and i could write the opposite about the Haix or Lowa, both are a bit heavy and a bit stiff for strolling over farmland.
