Hi, I ALWAYS get blisters on the balls of my feet when I walk a distance of a mile or more. There is only one shoe brand/ style I don’t get blisters when I walk distances, Sketchers Mary Jane style “flats”. I was very surprised when I discovered this, and initially thought it was the brand, although Sketches are known more as fashion shoes than athletic shoes, but I haven’t had luck with the more typical athletic styles they carry. I would like to find a really good walking shoe that provides more support as I have some hip, leg, and back pain that flairs when I walk a lot. I am 53, 5’5″ 165. I wear 7 1/2 , B width shoes. I don’t have any other foot issues. I was told by a shoe salesperson 20 years ago my arches had fallen, but I have no idea whether that was accurate, or if it is a permanent condition. Can you advise what may be causing the blisters and recommend some good shoe options?
