got these last year for xmass, honestly haven't put too much wear on them, maby 15 miles worth of walking in them around town and then 3 or 4  two to three hour hikes, but they haven't broke yet. I think a fair guess would be 1 to 2 years of everyday use or 5 to 10 years of use as needed, like I have been, I mean 1 year latter they still look brand new, and I have had some cheap $20 shoes from ross last me 4 years of almost daily wear. I think these will last me 5years or more :) they are comphy too I did 10hours of comunity service in these and my feet didn't hurt, did 10 hours in converse and 10hours in 2 diffrent types of skateshoes and my feet hurt with in 6 hours, so hands down the most comphy shoes I have

well here it is a whole 2 years latter and the dam things still look brand new!!! I try to hike atleast once a week too. They are veary close to being water proof, like you have to stand in water up to your knees and count to 3 befor you feel your sox get wet, so just walking in the rain or steping in puddles is not enough to soak through :) Im happy! well so far there is almost no signs of wear,slight mud stains at best, real talk some how they still look new, I got like 4 pairs of shooes siense then and these still look like my new shoes. I once thought they last me 2years max but now Im thinking I got about 4 more to go but if I step up my game and do more than a 2 or 3 hour hike and realy put these boots to work or go like 3 times a week then I'll get another 2, but I don't think most people get out in the brush as much as me or smash through creaks and use them as work boots from time to time too, sooooo I think most of you could veary well have these outlast your car or spouce lmao, some people might even have these for life, and Im sure most people will goodwill or throw them out long befor they fall apart. I had a good opion out the gate but these last 2 years they have made me 1 happy camper. Comphy too!!!! omg I can be on my feet all day in these! Im 29 most comphy shoe ever worn hands down, well that and my rebock pumps from 1st grade :P
