I have a wide foot and now I have an athletic support that should fit in my shoe. They're perfect for every CrossFit program I've done to date. I didn't run anything significant with them other than short 400 meter intervals, but I felt supported. They took a while to break in but they get better with every sock. I wish the heel and collar were a bit higher. When doing long jumps, I sometimes find that the leg sticks out slightly, but that may be due to the use of supports. Overall happy with the shoe and would recommend for people with wide feet who like stability when training.
