I have never worn K-Swiss so I wasn't sure the fit, I read all the reviews but no one mentioned width.  These were so cute and a great price I decided to give them a try.  Unfortunately for me, I have a wide little foot...shaped like a triangle or Fred Flinstone's foot  :)  They stretched a little; but they fit very similar to a Nike or Under Armor shoe, narrow toe box.  Typically I wear Asics  or Saucony; so if those are shoes that fit you well, then you may have the same experience I have.  Also, I wear these for fighting and cross training, not running, I kept them to wear around, I keep the laces loose, and they are comfy for that!!!!  They are well made and I get lots of compliments on them!!!  I wouldn't run in them!  The shape feels weird for running, but I have been running in the 5 Finger shoes for a while now and everything else now feels like bricks on my feet :)
