I like to wear sandals but due to my severely flat feet have not been able to do so comfortably.  I looked up these sandals and based on the reviews purchased them.  I was skeptical due to the unisex tag placed on them that they would fit and the complaints regarding sizing noted in the reviews were due to this.  I have owned the sandals for a month and found that after a brief break in  period they were a perfect fit, true to size and very comfortable.  I purchased two pairs and while a little pricey, I believe you get what you pay for and would recommend them for anyone looking for a "support" sandal.
