I got these for nursing school in size 42 N. I wear between a 10-11 in shoes, and have never really been a narrow, but run towards it. These fit me great. After ordering the medium width and sending them back, I tried narrow and sure enough, there is no slipping when I walk. The only spot I get a little rubbing is the top of one foot, but it has already begun to break in to where I don't notice. I walk about 1.5 miles a week to break them in, and the leather looks great still, no scuff marks. I had to get used to the height, since I wear flats or tennis shoes, which was the only "issue" I have had.
