These are awesome.  I wear them all over carpet, tile, hardwood, leather, concrete, rain, dirt.  I've had them six months bouth the 12 or 13 and they fit great.  I have wide feet too.  They show wear but haven't unthreded or torn.  Comfy, Warm, and fit in a ball.  I got them becaues they didn't have rubber on the bottom and these are nice.  They aren't substantial and the non skid bottom only goes so far.
