Having used these shoes on and off for over six months I've found they do a good but not great job. I sized these like my street shoe but in retrospect I should have downsized by a half size. They are far less sturdy than my Anasazi making for a much more comfortable out of the box experience but a less precise fit after break in. The rubber sticks well but I find they are not very supportive leaving my feet aching after harder sessions compared to other shoes: I'm not sure that the 'polycarbonate support' in the sole does anything.
The sole started to separate slightly after crack climbing in them so I'd definitely advise against using them for this purpose. The shape and heel means they edge and heel hook quite confidently. The soft sole makes smearing quite effective but doesn't support the foot in small toe pockets as well as others. The gel pad in the heel seems to be more of a novelty than anything else.
Overall I'd say that they are a reasonable choice for the price compared to the retail on others and well suited to a beginner boulderer/climber. Having said that I think I'm better served by keeping an eye on prices and getting a higher end shoe at a discounted price (still about $30 more).
