On Women's Cloudswift 2 Running Shoes

On Women's Cloudswift 2 Running Shoes, size 6.5. Worn 3-4 times at most. In excellent condition minus a little dirt on the back that can be washed off (see photos). I did not realize these should have been ordered a half size up and they are too small. I tried to break them in but they’re still too snug. They fit more like a size 6.
