I haven't looked at or picked up a pair of Asics since I got my Nimbus VII's like 6 years ago. And there's a reason for that.
My Nimbus VII's are STILL together, still functional, comfortable and showing no signs of breaking down. I also have a pair of Gel Lyte III's that aren't too bad, but man, those Nimbus VII's just won't quit. Compare that to a pair of $110 Air Max 180's I got at the same time, which just didn't feel the same after a 3 mile run.
I think Gel is one of, if the not the best cushioning techs out there, faaaaaaaar superior to anything Air-based, not even close. The outsole is still holding up and no frays, rips, tears, or anything. Granted, I don't wear them every day and I've only used them for walking, running and hiking, but they just keep on trucking.
