I have 4 pair and my wife has 2 of zamberlans, I think they are the best boots made for long lasting. I have not used the boots you are looking at, and don’t know your use for them.
I like the boa system for certain applications, but on a hunting boot it makes me nervous. I think for many things it would be fine, but if I was hiking a lot of steep country I wouldn’t consider them because I want many options for lacing to make sure I can get the fit dialed in, different boots call for different lacing techniques… I don’t have 2 boots I lace the same, and rely on versatility for lacing.
one example, the trail lite evo gtx, if I snug everything up evenly, it would chew my heel off on inclines, and get narrow in the toe box, if I leave the front of the boot loose and trap it that way and make the top 2 snug, they are incredibly comfortable… almost all boots are that way for me, just evenly snugged up is rarely comfortable, and that’s the only option you have with boas… the boots you are looking at have 2 sets on each boot which probably helps, I just want complete control over the lacing on any boots
if you are using them for stand hunting, they will probably be a kick ass boot
