All my shoes are size 9.0 or 9.5 in D widths. I ordered the 669s in 9D. After loosening the laces, I still had to give a decent tug to get my foot in. They toe box left me some room but the area acoss the top of the foot felt snug and was still uncomfortable even after wearing them for 48 hours. I took advantage of the free returns and exchanged them for the next available width which was EEEE. These gave me a comfortable fit. I am happy with them now and find them to be good walking shoes.
I compared the insoles between the 9D and 9EEEE. The EEEE was maybe 1/16" wider and 1/8" longer. The larger width is gained in the uppers and not the sole. Rating 5 stars based on fit and feel. Hopefully the quality of  longer term wear will achieve a similar rating.  Previously I had typically used running shoes for walking, but After "road testing" these shoes on a couple walks of 1.5 miles,i do like the elevated heel which promotes a smoother rolling action toward the toes.
