I looked everywhere for a mix between stability and cushioning to no avail.  Tried, New Balance, Nike -- finally switched to ASICS and ran in the Nimbus and Keyanus (or however you spell it) for a year or two each and I didn't like either (I am 5'10" and 170lbs, which is a bit light for both, I believe).  I run approx 20+ miles per week and run a marathon a year.  The only reason I have been able to maintain my mileage is because of this shoe.  For me, given my running nuances, this shoe has been phenomenal.  I have run several halfs and one full marathon in the Kahanas with zero issues.

I read some reviews that they fall apart quickly, wear down etc.  Some of it is true, but for the past 4 years of running in this shoe, I have consistently obtained 6 months of 20+ miles a week out of each pair.  I actually buy two pairs at a time and rotate them, giving me about a year.  Other running shoes cost about $120+ per pair.  I get two pairs for that with the Kahana and get twice the mileage out of it.  After a year, however, my Kahanas are worn down to the nubs on the bottom, but I have never had the fabric or any other part of the shoe fail.  I run on trails as well, which beats the shoes up pretty good -- still, I have yet to have a pair fall apart and I have been through 10-12 pairs.

This shoe is not like the GT 2160 or 2170s that ASICS has.  Those are true stability shoes and so their ride is much stiffer (I tried a pair and they gave me knee/ankle problems).  Again, the Gel-Kahana is a mix between the stability and cushioning.  Highly recommended.
