The Brooks Ghost I have recommended 2 years ago in the running analysis get (then Ghost5) and it is the perfect shoe for me. I have had no bubbles or other ailments in recent years. The Ghost 5 has been over 1000km and is still in use. Hopefully keep the new shoes as long. Compared to the Ghost 6 I find the Ghost 7 bit harder. But shortly after I started running, I no longer feel the shoe.
