Yes they run a little narrow but I have thin feet. I don't normally purchase a narrow shoe because they are ususally to small. This shoe is just right and I don't have to wear socks! they are so very comfortable - like being barefoot but with padding. I have the worlds most fussy feet and I love these shoes, they are sooooo comfortable. If you want to wear socks go a 1/2 size up but I would not say they are short.
