Love Crocs.  They are so comfortable to wear and for people with foot problems, they're wonderful.  I have heel spurs and I can wear Crocs for hours without any pain.  I've had the original Crocs with the holes for years.  Lately I've found I prefer taking my daily walk in Crocs instead of sneakers but the holes allow dirt and tiny stones inside, then I have to keep stopping to shake them out.  Saw these on Amazon and the price was excellent so I ordered them.  They fit like my other Crocs, just enough room leftover for a thin sock.  Perfect with or without a sock.  I agree with the reviews that say their feet sweat in these.  I will still wear my holey Crocs on the hottest days except for wearing these for my 20 min walk (sockless).  But for spring, fall and maybe early winter, these will be great.  So pleased that I went back for another pair in a different color.
