7.9 to 9.6 in a size 9 for the Kinvara vs 890 v6
I am not sure that is a like for like shoe comparison though. Maybe the 1500? That is 8.1
The Saucony's always feel lighter but they are also way worse quality in my opinion. They feel cheap. I liked the Kinvara but they were a bit skinny toebox for me.
