Built to handle the worst the wet valley floors of Sweden, this translates perfectly to the sodden marshes, moors and peat bogs of the UK.
I've yomped over the Carneddau, across the Migneint from Cwm Penmachno to the Arenigs, through the Lake District, over Dartmoor - I've also spent 5 wet, sleet stricken days walking near Storulvan in Sweden with 25kg's on my back, crossing rivers with these boots on - dry feet, the entire way, every day. (Obviously, like all boots, a bit of dampness from sweat can start to build - but i've learnt to air my feet half way through a long day in awful conditions.)
The Supa-fabric Haglofs use is no fuss to maintain, easy to clean before i take them off, and with the appropriate camp craft the sweat has usually dried out by morning.
Worth every last penny - if these fit you, you are a lucky soul...with happy feet.
