Hello,
  I've owned ASICS Nimbus dating back to I believe the Nimbus 10.  Each year they change them as always.  Well to start my running style is pretty good, no bad pronation etc.  I am a big guy, 6ft4 and about 220.  I run marathons and I need a good neutral cushioned shoe and the ASICs is it.  I also have Brooks Glycerin, and a New Balance that I forgot the number. Anyway, these new ones, #14 are a little different. I have two pair and I do love the new wild colors.  But both of these have required a longer "break in" period than any of the my others.  They seem pretty stiff, especially across the mid foot and the outer edges of the feet at the widest part.  I do like them, but you will need to put a few miles on them before they truly live up to the expectation of a plus hundred dollar running shoe. I really like the Nimbus so I am partial and these shoes are good. I am running a marathon in the next Sunday so that will be the true test.
