I prefer lightweight tennis shoes.  In fact, I often play in Asics volleyball shoes but the soles aren't nearly as durable as tennis ones.  This, so far, is my favorite tennis shoes.  They are lightweight and breathe well. I feel like I can run very quickly on the court wearing these shoes.  Plus, they match my black and pink Wilson racquet.
But while I am normally a size 6 in Asics shoes, I am a 6.5 in this particular pair.  So take that into consideration.  The very front of the shoes isn't really "usable" if that makes sense - not enough room for your toes. Finally, I am not sure why they discontinued this model as I think it is extremely comfortable and well-made !
