Jake Cwrote a review of La Sportiva Miura Vibram XS Edge Climbing Shoe - Men's on December 10, 2013
Familiarity: I've put it through the wringer
Fit: Runs large
I have climbed in almost every model of climbing shoe that Sportiva makes, and this is one of my favorites. I also currently own Solutions and TC Pros. Basically, while I can use any of these shoes for nearly any climbing application, I prefer to use the Miura Lace for outdoor sport climbing, Solutions for gym climbing, and the TC pros for long trad days. I wear a 11 US (44.5 EU) street shoe, but sized each of the models down accordingly:
Miura Lace: 42 (snug, not excruciating)
Solutions: 42.5 (snug, not excruciating)
TC Pros: 43 (comfortable)
Hope this helps!
