I love having Gizehs that I can take  into the water / wear to the beach. I'm a solid US size 7 and these true to my usual Birkenstock size (37). I've worn regular Gizehs for literally decades. This is my second pair of EVA Gizehs. I'm hard on shoes, and my first pair held up really well over 2.5 years. In fact, the sole on these holds up better for me than the sole on the cork Gizehs. Highly recommend.
