I was fitted in a running store for the ASICS 2160 last year, which was perfect for me.  Once I'd worn out my old shoes I wanted to buy the exact same shoe again.  This shoe is this year's model of the one I had before and it still works great for me.  I loved having some color choice this time around!  I use this for running and working out with Stroller Strides 4-5 times a week.  Previous shoe lasted about 6 months, I expect this one will as well.
