In reply to C Witter:

I would actually say that they are. So like I mentioned above, I have 510 Quantums with No Edge soles retrofitted to them... but I also have the exact same non-modded Quantums (well had). So ne thing that I found out, that the no edge one stays consistent performance pretty much from when you first slab 'em on, until you get a gash on the outer no-edge rubber. Where as standard soled shoes are first good at edging (and precise), since they actually have a nice precise edge on them... this will not last long though. So after a while you have a bad edge (and often loose performance). And finally you get another performance boost when the sole is almost like a no edge one... but that doesn't last long, before you get a hole in them.
That being said, no-edge soles are not perfect for everything... like a really small edge (dime sized) on slick rock. Due to the sole edge missing, you might not just be able to utilize it at all... instead what you need to do is smear around that spot... on sand stone, grit or in most cases granite, that might work ok... but not always. So when climbing with no-edge shoes, you are basically always smearing. You might stand on a small hold, but you're also smearing around it. Which can be beneficial, but not always (see above, small hold or small hold in a tight space).
And indeed one thing is, that pretty much all of the no-edge shoes are soft. Even Genius and Futura. So it is not suited for those that prefer support from stiffer soles.
Edited to add the point I was trying to make above (in my earlier reply)... is that at least for me, the main point with no-edge shoes, is that they give consistent performance pretty much for the duration of the sole. Where as with regular soled shoes, the performance is ever changing. You start with a really good sharp edge (great on small lists or standing in nubbins), but often the shoe has not yet been broken in (even if you resoled it). As you get more comfortable on the shoe, the edge is rounding off, so giving you worse performance then with a good one... this will continue until near the end when you have an effective no-sole due to all the wear. But that boost is often really short lived. So previously I went through a few pairs (or resoles) each season (spring, summer and fall outdoor bouldering and some roped stuff as well). Now I can often get a full season and indeed even majority of indoor season (fall-winter-spring) out of one pair of no-edge shoes (new or a resole). So I have a financial incentive, but also a performance one. And I also have regular soled shoes, so if a particular route or problem requires an edge on the sole... or stiffer sole, I have something for those situations... but I have not had to resort to that in the last 2 or 3 years IIRC.
