My green one is now extra short, oops. This hat fits great on my head. Rainy days are no longer a problem because of the material, and they look professional too - no one knows Im wearing Crocs until I mention it! I personally did not size up because I have a narrow foot and if they stretch, it will be too big. Also they start to smell bad, and they get real dirty easily. It is intended for the person who is considering paying for a top-of-the-line home entertainment system receiver. This case is perfect. In fact, I loved them so much I ordered another pair from Naot that are closed toe sandals. Also, 2 of the long screws provided for the main support were bent/ damaged. Im glad that Amazon has these because the nearest place I can find a replacement is 3 hours away.
