The first pair I received had a noticeable manufacturing defect in the right shoe. There was a large bump under the ball of the foot. I sent those back thinking it was a one-off. I asked for an exact replacement and the right shoe still had a bump, but it was much smaller. I have been wearing the shoes for a couple of weeks and can walk 3 miles without my right foot getting sore. I'm wondering if anyone else is experiencing this bump problem. I never had a problem with New Balance until I got these. I also noticed that the 4E doesn't seem to be as wide as it used to be, but then I have aged somewhat and my feet may be wider now. I used to be a 10 1/2 for decades. Now I'm an 11.  Update. About 4 months later I started having foot problems in my right foot. I quit wearing these shoes and have crossed New Balance off of my wide shoe list.
