These are comfortable for walking and wearing for strength training; however, I really purchased these for my cardio workouts consisting of hiit, circuit training and various cross training. I have not run in them because I have specific shoes for running. So, these did not quite make the cut for my dedicated cardio shoes, but for walking and weight training they are good. Be aware, part of the problem with these shoes is that they are a half size too large and I would have sent them back but I had already worn them for a vigorous workout before I discovered the fit issue. I wear a size 7 in regular shoes, 8.5 in running shoes, and I ordered these in 8.5 but should have ordered an 8. The half size makes the arch of the shoe not line up with my actual arch, plus in certain moves, my feet slide forward in the shoes which is uncomfortable. This has been my experience with the shoe. I might love it if it fit better on my foot.
