Nike Women's running shoe

Nike Women's running shoe. Unfortunately these run tight on me and I can't wear them. Only used sparingly for about a week. Size 8. Sole is barely broken in, same as the insole. Just needs a quick rinse! Comes from a non-smoking home, excellent condition! Keep in mind I am normally a size 8 and these were tight on me (at the toe)! Originally got for $80.
