To date all the reviewers, except one, ranked this shoe 5 stars.  I agree.  It's as good or better than the 2130 I put 340 miles on before leaving them at a condo in China (next trip I'll still use them instead of carrying my new 2150s).  There is a reason these are the best selling running shoe in the world - they are excellent in every way.  The person that stated his/her older version of these shoes are better is all wet - no way.  These are great shoes.
