I usually don't have too much trouble with running shoes. Only brand I avoid is Nike and it's only bc I'm between sizes, so I was shocked when I found these so uncomfortable. I experienced a lot of upper foot pain during a 3 mile run on pavement & dirt. Tried breaking in more and still the same. I also experience tenderness on the balls of my feet if I wear them too long. I've owned ASICS before but its been a while. Surprised.
