I have had Brooks Ghost running shoes for a while, this is my fourth pair. The Ghost 9 is very much like the Ghost 8. [Click here to see older shoe reviews.) The sole seems to be exactly the same. The upper is more stylish with pattern in the vent holes. The shoe is 335 g which is 10g lighter than the Ghost 8.
I like this shoe pretty well. Much more comfortable than my other shoes, which may mean that they are wearing out.
