Later in the year when I was hiking up Shepherd, I passed a group of 3 who were being guided up Williamson - the guide had the same La Sportivas.
Scarpas appear to be aimed at people with wider feet. I tried on (indoors) at least 6 different pairs of LS & Scarpas (from AMZ with free shipping & returns) before deciding on these (mens):

As a basis for comparison, I moved from a really wide NB trail runner to a really wide Altra Lone Peak 2.0 for regular backpacking. The Altras are the shoes I wore when I did back-to-back 30 and 32 mile days on the PCT last spring. (They are also what I run in every other day).
I've got around 150+- miles on the Scarpas, including a 12 miler in the Canadian Rockies (where I saw a woman in a pair as well) and a few 7-9 mile days in the local mountains. I absolutely love these boots because they fit almost as well as my Altras. The La Sportivas I tried (multiple sizes) were all just a little too tight.
The reason I got the boots was to be able to open up a bit more winter/alpine conditions. To that effect, both boots are designed to be able to use clip-in crampons as well - you can see the rear lip in each photo.
