i bought a pair of Scarpa Kailash GTX Boot a few months back and like them. I see some online for $10 right now. They are pretty light for a hiking boot and I don't know that they will last long, but they are doing well so far. Nice soft sole, sticks really well. May not be great for spikes, dunno. They also have some nice little ridges in the arch which grip the rope very nicely when footlocking. ALmost feels like cheating!
Of course, if you thrashed some Scarpas already, maybe you aren't interested in this advice!
I had a pair of heavier leather Scarpas, but their sole was so hard that it tended to tear bark way too much for the (mostly) pruning that I do on soft barked trees. They didn't tend to stick to wood very well either. So I had to put them back in reserve for actual mountain use. I bought these new ones sight unseen because Scarpa is a known brand that fits me well. That's the deal right? We all have different shaped feet, and one boot will fit someone great and another one horribly. Buy on fit and comfort instead of features is what i think.
Yeah, whatever you get, it will get thrashed working in trees. It is an expendable wear surface just like rope. Light hikers aren't made for climbing in wood non-stop, but the truth is that they stick really well and don't harm the trees whose health is the pride of my work.
of course, removals is a different deal...
good luck!
