I found the ww576 to be sturdy and supportive. They did not have much arch support but I took out the insoles and used  profoot inserts which has a built up arch support. I usually wear an 8.5 B width and these seemed true to size. They were tight the first hour and then loosened up nicely. No rubbing of seams anywhere and the tops of the heels did not dig into my ankles. In the winter, I wear thick socks as my feet get cold no matter how warm the house is and there was plenty of toe room. I might start getting a half size bigger shoe as I'm using the 3/4 size orthotic inserts now but want to start using the full foot inserts. I have fallen arches and sesamoiditis, these shoes really help. However, I do not feel like I'm floating on air as some of the gel shoe reviews claim. I don't know if that's good or bad. I read on the new balance website that these shoes do meet diabetic requirements.
