I just my A86 in the mail two weeks ago.  I was impressed right away with how light they are.  Talk about your minimalist shoe.  I felt like i put on a sock.  I've put about 50 miles on my A86 shoes so far.  I'm just converting this year to the zero drop shoe.  Here in Utah it's all the rage.  Because of the zero drop, you have to change your running form strike flat instead of a heavy heal strike.  That's taking a bit of getting used to for me.  They say they fit true to size, but i found mine to run about a half size small.  So far i really like the shoe.
Pro's
1.  Super light shoe
2.  Excellent fit and plenty of room in the toe box
3.  Pretty breathable.
4.  Well constructed and flash colors to choose from
5.  Trail Runner magazine really liked it and gave it an "Editors Choice Award"

Con's
1.  The ankle box is unusually large (From Heal to Laces)  I'm still undecided if i like it yet.

I will update my review after a couple more weeks running on it.
