I originally bought these in my regular size 8 1/2 to keep around the office. When I ride my motorcycle to work, my riding boots are uncomfortable for the rest of the day (they get hot in them), so I just wanted a pair of comfortable office slippers to wear when I commute to work. I bought a pair in my normal size 8 1/2 and they were a little longer than I expected. They are still very comfortable but I ordered another pair in a size 8 (1/2 size smaller than my usual size). They fit perfectly! I will use a size 8 for my office slippers and will take home an 8 1/2 just for use around the house. Besides the size, they are really very comfortable! I don't feel any hotspots and the cushioning is more than adequate. Can't comment on durability yet but they seem to be quite well made so I'm optimistic they will last a few years with light home/office use. The picture shows my Asics sneakers side by side (size 8 1/2), my Sonoma casual shoes (size 8 1/2) and my Nunn Bush loafers (size 8) lined up for comparison.
