Have you always gotten blisters from shoes other than soft sneakers? Up until I was in high school, I got terrible blisters from anything other than sneakers. I dreaded having to wear nice shoes for church or a special occasion because it was so painful. One day I was standing in the kitchen barefoot, and my mom said, “What is wrong with your feet?” She thought my heels looked strange. They’d always looked that way to me, and I guess she hadn’t looked closely at my feet for a while. We went to a podiatrist and it turned out I had something called Haglund’s deformity. It wasn’t nearly as grotesque as that name sounds. It’s kind of like bone spurs. A quick outpatient surgery took care of it, and since then I’ve been able to wear all kinds of shoes with no problems.
If you’re sure you don’t have some kind of foot condition like bone spurs, you might just need to be fitted properly for shoes. Try to find a local shoe store that will completely measure your feet. There’s a shoe store around here that is owned by a podiatrist and he takes several foot measurements and examines your feet before suggesting shoes.
