A friend of mine bought a pair of those boots and got rid of them because they tore his feet to shreds. They are OK if you wear them for ice climbing ( 1-2 short routes at a time). But don't try to walk more than 5 miles in them. In short go with a quality boot.
I totally disagree with the above. I have these boots and they are amazing. I use them for every winter climb & hike. I've done 20 mile days without one issue. It's a matter of getting a boot that fits you correctly. They fit me perfectly.
