A bit late for reply - but glad you like 'em. 4lbs?? mine are closer to 3, and they are much lighter than the steel toe safety boots I wear all week! So I use them for both day and 4-5 day long BP trips. $25.00?? if I find another pair that price they're mine!
I have a pair of Zamberlan Goretex lined boots that I used for years, and they are no lighter.
Like I said, I'm kinda old school about some things
Happy hiking!
