Dior B23 tennis shoes 
These are men's size 6   39 EU  but would fit woman 8 to 8.5

Look carefully at the pictures.  The tab on the back of one shoe is torn off.  You can do the same to the other side or just use it that way.  No one but you is probably going to notice.  So you'll get a great deal on an expensive pair of shoes due to this little flaw.
