Leonie C.wrote a review of La Sportiva Sparkle 2.0 Alpine Touring Boot - Women's on March 11, 2017
Familiarity: I've put it through the wringer
I have the original version of the Sparkle from 2016. I'm 5'7", 127 lbs with low volume feet/ankles. I tried on everything I could in the Seattle area, and only this boot fit. With about 75 days in them, I still love them. The only issue is some slight pinching on the left ankle which is as much a function of 4 ankle surgeries as it is a problem with the original version of the boot which has been addressed in the 2.0. I've used these boots for inbound, backcountry, and a skimo summits to include Shuksan (WA) and more recently Whitney (CA). I left my ski crampons at home for Whitney so spent the majority of the ascent in the Sparkles with my crampons (Petzel Lynx...see photo)..about 8 miles and 6000 vert ft of boot/crampon joy. The boots were phenomenal. The walk mode is amazing. They were just fine scrambling up some class 3/4 rock, and kick step up When it was finally time to get some turns on the way down (yay sun!), I appreciated the stiffness of the boot especially with a heavier then normal pack. I will absolutely buy this boot again if it's still available.
