Nike dual fusion running shoes

I've had these for awhile and made pretty good use out of them but they are still in great shape and need a new home! I am a women's size 7 but these are a 6Y and fit perfectly. On one of the Nike swooshes there is a little tarnishing and on the white part of the bottom there is visible use (as shown in the pictures). However I have gotten a new pair and figured if someone could use them then I should try to give them a lot more use!
