I only walked around the house in them a couple of times (carpeting only) using Dr. Scholls inserts to see if that would work, but it only made it worse. It was too late for me to return them by the time I got back from Italia. I LOVE them, but didn't want to size any smaller otherwise my toes might get crammed!
