I got these for my husband who usually wears 4E/extra wide. They were, overall, far too small. I think I would recommend to size up up even if you have narrow feet.
Perfect replacement for a pair of slippers that I used for business travel. I have had the ones replaced over thirty years, using them just for travel. They finally were just about to fall apart, and had become embarrassing to look at. The LB Evans feel and pack for travel just like the ones replaced and the comfort level is the same. I may buy another pair for around the house.
