that's my third generation of Kayano, after T100N, T200N. It's quite soft and very confortable for running on natural grounds. I'm 1.96 mt x 85 kg, and my joints react very quickly if the shoes are not the right one, in this case i'm having fun without any problem. Being quite soft, after 18 month of use (2-3 times a week) the profile deterioration is very advanced, so i'm not reaching two years; maybe it's normal, don't know. Fits like a glove :-).
Anyway i'll buy again a Kayano!
