This shoe is amazing on certain rock types and styles, calling it an "all arounder" is pushing it though. It excels on plastic, sandstone, and granite that involves mostly smearing/smedging. Anything that involves a heavy amount of toe and heel hooking this is what I reach for. Previously I used skwamas for those problems, the drago is significantly softer and lets me get more rubber into the rock. The soft heel cup deforms into the features of rock better than the skwama and inspires more confidence. On rock that involves smearing these might as well be cheating, you can get so much rubber in contact with the rock. In the gym they excel on volume/comp style problems and being so soft they are great for training foot strength.
Now the downside, let's take this quote:
"thin and flexible Vibram XS Grip 2 sole gives you the ability to edge on micro edges and smear with confidence"
I have to laugh at the first part of that, you can't have your cake and eat it to. You don't get the most sensitive shoe on the market and have it do micro edging, sorry. I will say that *for the degree of sensitivity* this shoe edges fairly well (compared to teams of maverinks), however there is absolutely no midsole. Most all shoes have a some type of midsole under the toes to provide additional stiffness, which provides the platform to edge. If you want a bit more edging ability the chimera has a TPS insert that goes across the toes only (no ball of foot, still killer for smearing). When it comes to edging on slab to just slightly overhanging rock the drago flat out sucks. If you're on a slightly overhanging route that requires you to pull with your toes in a high rockover they just don't do so hot. The best shoe in that department for me has been the testarossa (it's like having talons with friction). I wore the drago and testarossa back to back and then with one model on each foot on a sport route that required mostly thin edging and had a lot of those rockover moves, the pump was far less with testarossas on. Also tried them back to back at the gym one day on a problem that had only single wood screw jibs and features of wall for feet, the testarossa allowed me to float without crimping hard, had to bear down on my fingers in the drago.
So in summary, if you like sensitive and soft shoes I'd recommend these for 99% of plastic (especially steep bouldering), steep sandstone, granite bouldering that requires mostly smedging, anything hooking intensive. If you don't have strong feet these will not work well for you.
I do not recommend these for limestone, granite with angular features and low friction, serpentinite, or any thin edging route.
