Hello,
I am from Britain, I have had a couple of pairs of Altberg Boots, the Defender, and the Field and Fell Boots, I found them good But I have found that their Sizing is Crap, in one pair a UK10.5 was Too Small, and in another, a UK10 was Too Big.
I now wear a Pair of Lowa Combat Boots, they are Brilliant, really well made, and great for Tabbing, they are Very Popular with British Soldiers, But I am about to Buy a Pair of Hanwag Military Boots, because I prefer their Lacing System, I do not like the Speedlace Pegs on the Lowa boots, as they are Not good for Parachuting, but if this is not an Issue, then Either Boot is Great.
Hanwag boots are £120 with military Discount from WWW.campshop.co.uk
they will post them to you, they may not be shown on the Site But Email the Owner, he does sell them.
I recommend either Lowa or Hanwag over any other Military Boot.
Regards
Rich
