I purchased my pair at a local shoe / camping / cycling / everything outdoors store (guess which one!).  But I felt it wise to put my two cents in here.  I tried on 13 pairs of shoes.  Seriously.  I have used Asics for a long while and am partial to the brand.  Trying these on next to the Asics Gel Kayano, you can really tell a difference.  The Asics seem to have a little bit too much plastic and feel odd. (Yeah the Kayano is a support shoe as I found - seems that some periodicals have them covering neutral runners also).

For a neutral running shoe it doesn't get much better than this.  The shoe is light and responsive.  So far I have put over 100 miles on my pair and they feel good as new.  I run 7-9 miles every day so durability is important.  If I am having a sore knee day I switch to the Brooks Ravenna.

But seriously, try a pair on somewhere to gauge the sizing accurately.  You will be glad you did.

Update 3/2011:

As mentioned in my comment: I use neutral shoes 90% of the time, but an IT band issue last spring forced me to ease back into running.  I went with the Ravenna for awhile until my natural stride resumed.  I would use them on sore knee days (they have about 300-400 miles) so that I don't unthinkingly adjust my stride to ease off the left knee and over pronate.  I also purchased a pair of Brooks Launch and Saucony Kinvara and love them.  The Ravennas have since been retired.  The glycerin are still in my rotation and used for outdoor pavement running.
