So I have ran in the Kinvara 3's for about a year and a half and absolutely loved them. When the 4's came out I heard negative reviews from a lot of people and from a lot of sources so I stuck with the 3's as long as I could and then the Nike Structures for a couple months (trained in them a lot before the Kinvaras). Looking to go back to something a little bit more minimalist than the structures and now that the 5's have been out for sometime, what do you all think of them?
