I have a pair of Sanuk men's slip ons and i love them.  they are the most comfortable shoe i own.  the foam footbed can be a little sweaty in hot weather without socks, but still, extra comfy.  So i decided to branch out and ordered a pair of womens.  It is beyond me why many footwear manufacturers insist on making women's shoes so much more narrow than men's styles.  Porportionally, women's feet are actually wider than guys!  So why don't we quit with this sexist, pre-20th century Japan crap and make women's shoes so that they fit comfortably.  Get with it Sanuk.
