I loved the feel and fit of the Precision 11's the moment I worn them.  Bought a second pair and after just about a year and 1000 miles, realized I have worn them out. Blisters in new places.  Nagging hip soreness......  I could not find another pair of Precision 11's in my size, so ordered the new issue Precision 12's, along with the Musha 4's.  The new issue Precision 12's are totally different.  I can't stand them, and sent them back.  I think the Musha 4's are more like the old Precision 11's, than the new Precison 12's.  Less support, lower heel, a bit lighter.  These are just a faster shoe. I wanted to try a more minimal shoe, with lower heel, and these are prefect.  I was a bit concerned about having less cushion, but after my first 12 mile run, no issues.  I plan to marathon in these next weekend.  A really bright shoe, but I like em!  Just ordered a second pair from Haloway Sports.  The first pair I ordered on Amazon, 10 days ago for $80.50 Prime.  Today the price was $86 while I found them free ground delivery from Haloway for $75.95.  Great price.

8/24/12  I've worn these for a full marathon and two half marathons.  With training, I have about 1000 miles on the two pair I rotate, this year. I couldn't be more satisfied with this shoe.  The price has dropped a bit to a best $69.00 free delivery.  I intend to buy two more pair.
