Once again ASICS rock!  I love this pair of shoes.  My old pair of ASICS were great also, but they just had too many miles on them.  I like how lightweight these are.  One thing I have noticed is they are good for a couple of miles, but then the shoe looses its effect.  I am not sure I would purchase a pair of these for marathon running.  Perhaps, it isn't the shoes causing this problem.  I just know they don't feel the same once I have ran over 3 miles.  Other than this, these shoes are excellent!!!
