Grey suede slouch boots

I bought these from another seller. I included screenshots of her original listing photos for reference (pics #6-12). I never wore them because they didn’t fit. I’m a size 7 in boots but took a chance on them. The seller was assuming it was a size 6. Wish they fit because they are beautiful, well made, and in great condition. They do have a stain around edge of interior fabric (looks like self tanner- pic 4&5). There is no visible size on the boots. Original seller assumed it to be size 6. I think it’s 6.5 because it was just a little snug against my toes with socks on. Again, never worn after purchase, only tried on with socks. Selling for how much a paid for it.
