MY HUSBAND WEARS A 7 1/2 MEDIUM - I ORDERED D, WHICH I AM NOT REALLY SURE WHAT THIS IS; IT ENDED UP BEING SO NARROW, HE HAD TO WEAR THEM AROUND THE HOUSE FOR ABOUT 2 WEEKS BEFORE HE COULD WEAR THEM OUTSIDE - THEY WERE TOOOOOO NARROW.  SOMEONE PLEASE TELL ME WHAT "D" MEANS - DID I BUY NARROW AND NOT KNOW IT???? HUBBY WOULD NOT LET ME RETURN THEM, HE SAID HE WOULD BREAK THEM IN AND SEEMS THEY HAVE STRETCHED A BIT NOW.
