  • OK, but disappointing

    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).

    Not made for forefoot strikers at all, also the tiny spikes on the shoes if you ever clip your calf’s be ready for a big hot rash.
