These slides are really soft which makes them really comfortable when walking.
However, they do run huge both length and width.  Definitely order a size smaller.  I usually wear size 9 (women's), read other reviews and ordered size 8.  They fit fine length wise with some room to spare.  However, they are still big width wise.  I have normal feet, not wide and not too narrow.  They don't really slide out in front when walking but look and feel really wide.  I am keeping them because they are comfortable to walk in.  Adidas, please start making slides with adjustable velcro on top again.
