These have quickly become my favorite shoe of all time!  Depending on the shoe, I either wear an 8 1/2 or a 9 and ordered a Sloggers size 9.  Perfect fit.  (I did read all reviews before purchasing this clog because I know quite a few people had issues with size.)  If you wear a 1/2 size, I suggest ordering up.  The inserts are removable for washing and the clog itself is easily hosed off.  I'm glad I chose this specific Sloggers clog - it is so comfortable & it suits me perfectly!
