True story: my mate climbed the North Buttress of the Chardonnet in a pair of those (with crampons strapped on, obviously). So it's the 'man in the boots, not the boots on the man'.
Myself, I prefer Scarpa boots - but only because they fit my feet nicely. And I have never had any problems with them.
On the other hand, my missus has had to take _three_ pairs of Scarpa walking boots back over the past two years: the soles keep coming off. The claim is 'it's a bad batch'.
