The previous Infinity Run models were fantastic long run shoes with a slightly firm, but very shock absorbent foam, a lot of cushioning, and a nice smooth rocker. I've run multiple 16 mile runs and one 20 mile run in them and they don't lose comfort during the run and leave my legs and feet feeling great. They were also very durable. The Infinity RN 4 has a softer foam that has a little bit of bounce, so the rocker isn't as smooth (though it's still effective). There's still a lot of cushioning and shock absorption, but my feet don't feel nearly as good in it (especially in the forefoot) and it feels incredibly heavy, which my legs really notice past 8 miles (but notice at least somewhat the whole way). I don't dislike it enough to return it, but I think that I will struggle to get miles on it, as I probably won't have it in my regular rotation, and will probably save it for mid-length long runs (8-12) miles and use something else for longer long runs (like perhaps my Infinity Run 3's which even with over 500 miles on them still feel better than the brand new 4's).

Like walking on a marshmallow! I wore these to Disney World from rope drop to the fireworks and my feet felt great! Can’t wait to run in them

Best supportive shoe hands down! I have mild pronation and these help me keep running everyday. The flyknit is so comfortable and I love the padding around the heel and tounge. Love the easy rolling smooth rocker when I run. Also the best walking shoe you can wear for casual use. I just had to go up half a size and it fits perfect.
