Blundstone are traditionally working boots but they've come out with an outdoor boot called the Mountain Master or something like that. I think the model no is 406..
Anyhow, from what i've seen they seem to be made well enough. THe one thing that did concern me was that unlike the European companies like Scarpa etc who try and use one piece of leather where possible, blundstone have a lot of stitched parts so they may be more prone to letting water in if not properly sealed.
Their soles and footbeds are terrific though and you can easily wear them for a whole day without getting sore feet.
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming "-- WOW--What a Ride!"
