This is the 4th generation of this shoe that I have bought and I am sad to say it will be the last.  I bought this shoe because I am an under pronator and need the extra cushioning and support.  I have run twice in these shoes and both times I was limping by the end of my 3 mile runs. Asics obviously changed the formula as some of the other reviews have mentioned.  Chalk me up as one of those that will be switching shoes.
