I’ve found that Skechers Ghenter Srelt Work Shoe slip-on to work best for me. They have a lot of cushion (which I need because walking barefoot is uncomfortable) and are slip resistant for safety. They are Medium width - I have narrow feet too, but have difficulty finding the shoes I like in Narrow. But these Skechers are snug enough with a sock of decent thickness, and the shoes come up high enough along the foot to give my ankle/heel support to help provide the best support for my walking around. Good luck finding the shoe that works for you!
