And the 'rocking' feel found in the original GOrun is gone. I find a much more stabilized feeling in the GOrun2 in this aspect, without any compromise to the support.
The placement of GOimpulse sensors are still there and they are suppose to offer flexibility and feedback for a responsive feel, although I must say that technically I do not feel their presence at all. All I can say in layman terms is that in most cases I really enjoy the good cushioning that these shoes are offering, at the same time they provide me the necessary 'firmness' that I prefer when I run my tempos.
One thing though, just like those expensive racing tyres you might have in your cars ..those Michelin or Conti ...and the likes, these shoes can wears out pretty fast depending on your landing style. So if you are new to racing shoes, be ready for the fact that this is pretty common for most racing shoes. I guess that is a trade off for better performance.
