Wife had to return the first pair. She normally wears a size 8, but after walking around the house for a couple of hours, she said they were uncomfortable; a bit tight on the width and heel. We exchanged them for an 8 1/2, and they fit her just right; not too tight, not too loose, and enough room to wear thin socks on cool mornings or nights. To rate the size 8 1/2...we would give it 5 stars; excellent fit, excellent stitching, and workmanship. (Hiking in the rain forest next month; will tell you how they held up in El Yunque!
