These are the worst pair of New Balance I have ever owned. Don't buy if you have flat feet. I've been wearing them with pressure-relieving insoles since I bought them. Took them on family vacation this week and after a few hours of walking they had blisters on their arches. I had never had blisters on my arches before, they stopped hurting which made the next four days in the magic kingdom very painful. They will be thrown in the trash when I get home as I have long passed the return date.
