Ashley Clementwrote a review of La Sportiva Miura VS Vibram XS Grip2 Climbing Shoe - Women's on September 8, 2014
Familiarity: I've put it through the wringer
Fit: True to size
if you're looking to upgrade, these shoes are worth a try (I wouldn't recommend them for a beginner). When I switched, I was instantly more confident on harder grades and noticed a significant change in my climbing. This toe will stick to just about anything. These are ideal for bouldering and single pitch.
Sizing is tricky and such an individual thing that its impossible to give advice on what to choose-- I can comment on how they fit over time. I talked to a lot of other climbers about the stretch of their miuras because I've had La Sportiva's stretch on me before. Some guys told me theirs had stretched, but I haven't experienced much stretch with mine. There was a break in period (painful, but worth it!), but no stretching, they have remained snug!
One and only complaint: the flower design, my pet peeve is when companies make women's outdoor gear girly. Luckily, its not as noticeable once they get a little dirty!!
