Update 3-13-2014:
Still going strong. They haven't come apart at all except for one small spot of rubber that has broken right by the toe-bend/velcro strap intersection; standing in camber shoes will wrinkle the toe area and cause the cracking. I usually avoid standing in them too long for that reason. They feel like well worn gloves, perfect on me now. The heel fit issue I had at first is all but gone. I still have plenty of rubber, no signs of holes coming yet. I still use the cedar bags and occasional washing (twice a year)to stave of the bacterial infestations. They are not as super-new-fresh as they used to be, but they are far from repulsive or disgusting. Again, I highly recommend using those cedar bags.

I'm wanting to add another more aggressive shoe to my quiver... maybe some La Sportiva Solutions or Five Ten Teams... then again, these are so comfortable and versatile that getting another pair isn't high on my list. I'm curious to see the next evolution of this shoe from Sharma.

Update 4-4-12:
Shoes have been holding strong. When they get sweaty, they dry out pretty quick and seem to resist stinking if they are properly aired out afterward. These shoes thus far have remained smelling like fresh leather which they are lined with. I recommend using cedar chip insert bags in the shoes after climbing to help fend off odor and help absorb moisture. Look them up here on Amazon.

I had a few scant instances on flat walls that showed a bit of slippage from these shoes on tiny holds. This is only a by-product camber shoes will suffer from as they are designed for inclined surfaces. My Anasazis handle flat walls just a tad better. This may be obvious to many, but I thought I'd point that out. Still I'd rather wear the Shamans and deal with it since the comfort is superb.

My street shoe size is 44, but I wear 44.5 or 11 in Evolv and Five Ten for a snug fit. I ordered the size 10.5, but exchanged for the 11. I bought these to get a more aggressive cambered shoe and for the quick velcro closure so I could relieve my feet between climbs. I had a broken toe last year and it still is a bit annoying, especially when laced shut for 2.5 hours of climbing. Here's my experience:

Fit:
Snug, Comfortable and glove-like. The toe-box is very comfortable, accommodating and is leather lined along with the insole. They even lined the top of the toe-box with the soft leather. Brilliant! The Love Bump under the toes gives the shoe a nice fit which translates into grip. The padded tongue is soft and comfortable too. The only "gripe" is that the heel comes up a tad high on my heel. I have a slimmer foot, but not waif-like. Just low body fat on me. Nothing to kill my experience at all. Support is very good, not too soft, not too stiff. Camber is about right too, in my opinion. I can wear them for a few problems then relieve the pressure for a minute, no problem. Even with the "pressure", the shoe is still comfortable.

Performance:
Sticky rubber. I climbed up to V4 on these last night. The toes edge and hold small features well. They also smear very stable as well. I personally felt that the rubber was noticeably stickier that my Five Ten Anasazi Blancos. I still have to get used to toeing with these on overhangs, but I did feel an added benefit from these instantly. Heel hooks... no sweat. These are less baggy than my Five Tens. I didn't think it was that big a deal until I heel hooked with the Shamans last night. Makes a huge difference. Awesome. I'm upping my game with these.

Aesthetics:
I have the Rasta Shamans. That's red, green, and yellow velcro straps and black shoes. They look pretty sweet, but I'm not a rasta type guy so I'd prefer one color for the straps. I would give the colorway choice 4 out of 5 stars. The shoe does show its intent with its downturn camber and obvious toe-box/Love Bump feature. Purpose/function built aesthetics are welcome in my book. Even though I teased about the Ras Trent-ness of the shoe (which I edited out to make more vegan friendly), they do instigate comments from bouldering crew at the gyms and I still like them too.

Give em a try. Nice shoes.
