In reply to Fraser:
I've just got a pair through the post and will be writing a review of them over the coming months.
First impressions are that they do, indeed, feel different to any rock shoe I've ever tried (and I'm not just saying that!!). Kind of like a sticky rubber sock, very soft and actually remarkably comfy - particularly for a super technical shoe (something I usually associate with agony). Furthermore, they are nice and sensitive out of the box, I didn't feel like they needed the usual period of wearing in that other boots require which was quite refreshing/unusual.
That said - and I know this might seem obvious - they are obviously a specialist shoe focussed on performance bouldering and sport climbing. Having just got back from a week away in Fairhead I couldn't see myself wearing them on the long trad pitches out there, your toes would be agony by the end!!
With regards to the no-edge design/technology, all I can say is that they climb well so far. I'm as cynical as the next person when it comes to marketing lingo/chat, so don't worry - I'll keep you posted (after I've done more than two routes in them)!
p.s. it's worth mentioning that I haven't actually succeeded on either of the two routes I've been trying in them, with their futuristic design I was - at the very least - expecting to jump a grade or two
