THESE ARE GREAT.  REGARDING THE SIZE ISSUE.  I WEAR A 7 BUT TOOK THE ADVICE OF OTHERS AND ORDERED A 7 1/2.  THEY ARE REALLY HARD TO GET ON BUT ONCE I DID MANAGE TO LOOSEN THE STRINGS ENOUGH TO GET MY FOOT IN, THEY WERE TRUE TO SIZE.  IN OTHER WORDS I HAVE LOTS OF ROOM IN THERE SO THE 7'S WOULD HAVE FIT BUT GETTING INTO A 7 WOULD BE REALLY REALLY HARD.  SO BOTTOM LINE - GET THE BIGGER SIZE.  THEY'RE REALLY COMFY.
