Ladies Nike Lunarepic Flyknit 2 Sneakers

These Nike sneakers are lightweight and great for running. Wore these a handful of times indoors - but ultimately preferred another pair of sneakers and these got tossed in my closet. Practically brand new, don’t have the box anymore though. Size - 8. There is a mark on the inside of the left sneaker, by the heel. It was purchased that way. See last pic. Any questions, just ask.
