I ordered my size, 7 and 1/2. They felt small, so I went to a local shoe store and asked if the shoes ran true to size. I was informed that the shoe comes only in full sizes.
I have had my Keen Newports for about 6 years and decided to try the Venice Keens. They are really nice and the blue color matches everything. I like the newer insole that is softer, plus they are odor resistant, unlike my old Keen Newports. They are very comfortable and I forget that I have them on and wear them for about 16 hours a day. They wear like iron. I usually take size 7 1/2 in shoes, but bought size 8 because they to tend to run a bit small.
I love my new keen sandals. They are extremely comfortable. And I must admit I bought them for their looks, and I really like the blue color. I know they will last a long time since they are very sturdy.
