I've purchased the Nimbus Series shoes for years now, so I am a bit biased but I think these are the best yet.  I purchase this particular shoe line as I find it is the best performance shoe for my foot type (medium to high arch) and running style.  It has sufficient cushioning and the asics website notes that they shoes have dropped 3/4 of an ounce in those model, based on new material adjustments.  They are very lightweight and comfortable, so for performance they get an A+ from me.

I've had problems in the past with long term durability of the Nimbus line, and I often find the mesh in the front will wear down at the toe and I will have to replace the shoes after a shorter time than desired.  So far with this model I am very happy as this issue appears to be corrected (so far).  Jury is still out there, but the shoes appear quite durable so far.

Style wise they gave me four color options which was more than they have previously to my knowledge.  I went with the black and they are nice, understated sneakers that don't stand out.  The other options are quite bright and I would find them unappealing to walk around with while not running, but the options offered give you enough options to find something you like.

Overall I am really happy with these shoes and will continue to be an Asics / Nimbus series customer.
