Elyse Saugstadwrote a review of Tecnica Mach1 105 MV Ski Boot - Women's on January 17, 2016
Familiarity: I've put it through the wringer
The womens' Mach1 105 Freeride boot is the gold standard for women who want a high performance ski boot. There are small tweaks to this boot that make it specific for a female (like a lower cuff) but with enough beef to it that you don't need to switch into a men's boot for a more heavy duty flex. I was previously in Tecnica's race boot, but I was very happy to switch into this boot just for the sole alone- race boot soles are slick as snot and these boots have grip to them for scrambling around on rocks/hiking and better grip for snowmobile-skiing. Plus, it's easier to walk across parking lots in these boots ;-)
I made the small modification of switching to a Booster strap for more direct power transfer.
The fit is like a normal ski boot, I don't know why it's saying above that it runs small.
