I've been training in Asics for a long time using the DS Trainer and Nimbus. The majority of my miles are in the Nimbus. I started having a new knee pain while training for a marathon and thought I'd try introducing a new shoe into my rotation.

Not surprisingly the GT-2160 didn't solve my knee pain but it was a nice change. I'd describe it as a middle ground between the DS and the Nimbus. It is not as responsive as the DS but it is softer and more structured feeling. It is less soft, but still more structured feeling, than the Nimbus. I'm taking off a star for a certain dull/woodness in the feel. Of course all of this is hugely subjective.

I will say the price is right on these. It's a great shoe for the money.

Bottom Line: I'll buy another pair.

For comparison I'm fairly unremarkable runner (low/normal arch, average width foot, neutral ankles, slightly external foot progression angle, heel striker, 65kg, 25-75mi/wk).
