I accidentally ordered the wrong size on the first pair and had to send them back.  I ordered another pair, and the size I normally wear was correct but they are very tight.  Probably should have ordered one size larger.  These shoes are not comfortable.  In my opinion, the unisex slider looks more like a women's shoe...the quality seems to be there, but the sizing seems off, and the comfort is soooo disappointing....hopefully they will get a little more comfortable with wear...not impressed at all so far!
