Received them today and immediately put them on...and haven't taken them off. I wear an 8.5 medium width in most of my shoes, wear 8 in some sandals and prefer 9 in boots so I can wear heavier socks. Ordered these in a size 9, and they are perfect. They are snug around the instep ( but not uncomfortable), so that may be a consideration for those with hi instep concerns. I think they would be perfect for someone with a narrow foot. They do require inserting an index  finger into the back of the shoe to get your heel in. Plenty of room for toes. Was lucky to find an Amazon warehouse pair in my size and saved a few dollars. They arrived in great condition and very well packaged. Oh, and the print is very nice. Very pleased with my new Sloggers.
