The Spectre's are great shoes that excel in all climbing disciplines.
Comfortable and precise, these have been my "go-to" shoe for my hardest sends.
But they are also comfortable enough to wear on multi-pitch routes.
The softer acopa rubber does tend to wear a bit quicker than stealth or vibram, but the extra stickiness makes up for it.
As far as durability goes, I have had they same pair for almost five years now, resoled them three times and replaced the laces last month for the second time.
Brand new they are stiff and a bit clunky feeling, but give them some time and they'll soften up. To me they feel a lot like Miura's, but without the baggy fit in the arch.
The only bad thing about these shoes is the price was jacked up about $35, two years ago.

I LOVE these shoes. The natural rubber wears a little faster than than the synthetics, but the Spectre makes up for it with its stick. These are my favorite shoes, I wear them whenever I want to be sure to stick to tiny spots, or if I am working a harder grade than usual.

I'm not sure what the other reviewer meant by purchasing these as a down-turned shoe. They're pretty flat out of the box. They're definitely a great sport shoe, excelling on vertical and slightly overhanging terrain. Due to the fact that they are not super downturned, nor do they have an aggressive point (like the LaSportiva Solutions or the Five Ten Dragons), they are not as strong for pockets or purely overhanging climbing, but the friction of the rubber makes up for that. Pretty comfortable as well, I wouldn't mind wearing them for a few pitches of trad, though I started to pop the heels after about the 10th pitch. An expensive shoe, as all high-end shoes are, but I feel these are worth the money.

I bought the shoe because it had a more aggressive downturn. I climbed 4 indoor climbing sessions in them and they were flat.
