I guess "it's not all about the price tag" after all.
I have high arches and a very slight over-pronation (not a common combo). I have great half-rigid orthotics, but it's not enough without the right shoe. I tried all the neutral premium shoes on the market: Nimbus14\Glycerin10\NB1080V2 were too mushy. Mizuno Enigma2 was nice at first but pretty stiff after several weeks. Mizuno Prophecy is OK but not that amazing, too (Mizuno implement their Wave tech with cheap stiff plastic- they have something good in their hands but they don't make it work). After trying all the major neutral premium cushion shoes, I've decided to try the *slight* support shoes category, since I do over-pronated just a bit.

This is a huge change, it just feels like my foot gets less impact on high endurance running. It's probably the best shoe I ever owned by far. The upper is also SUPER comfy. When it comes to uppers, I've realized Asics are truely the best (for me).

BTW I even tried NB 2040! which's stated as neutral but feels very heavy & has way too much support. I think this Asics GT 2000 competes with Brook's Ravenna, so I recommend all of those slight-pronators like me to try them both. It really does change your whole running experience.
The UK version has nicer colors! I hate it that US always gets the too flashy editions while Europe wins the conservative ones.

Size: Snug. I'd even say 1 size smaller than normal.. My GT-2000 US 11.5 fits like my NB1080V2\Glycerin10 size US 10.5. I've noticed that Asics goes towards the snugger fit lately, in general (their Nimbus 14 is half size small). I don't understand why companies don't keep the sizing issue consistent.

I can't comment on durability yet but I promise to update in a month or two.
