The thing is to use the name "Gore-tex" the Gore company demand a pretty high set of standards have to apply to the construction of the item, be it a jacket or boots or whatever, so the material itself isn't the important thing-it's been out of patent for decades and some alternatives are at least as good- but you are paying for a guarantee of a little more care in the manufacture: I don't know know if that is worth the extra, but you do know you aren't getting junk if the Gore-tex label is legit on a product.
I’ve tried Merrell boots twice over the last 10 years. Both times they have let water in inside a matter of weeks.
The price is good for a Vibram soled boot. They appear to be too flexible, does not have enough forefoot protection for rocky mountain hiking and I wouldnt trust the sole on wet rock but the boots get good reviews. So at this price it is definitely hot. They should last a good many years and 5 years down the line you should use some waterproofing spray to reproof the boots. These boots are a little narrower than usual. I would get them at least half a size larger than normal anyway to allow for extra thick socks. best to try them in a store as you may need to go one size up because of the narrowish width.
Other sites which track price suggest this is not a deal, they’ve been this price for months, the RRP is just nonsense
Heat OP - as I can clearly see quite a few posts praising the quality but some mixed / neg reviews also. As to gore-tex, I have to be honest bought some real leather boots a few years ago. Occasional wax polish and protect spray and they’re lasting good. That said I only walk in them, my 2 wheeled days are curtailed at present.
