BORN leather flats

Adorable and comfortable flats by BORN. They are leather and I've never worn them. I bought them a couple months ago and the stores had closed so I never return them and I took the tags off already so I don't think I can. They're just too big on me because I'm a 6 in they were 7 but I was hoping they would fit. The Hill is slightly stretchy so it's probably a better fit for 6 1/2 and 7 maybe up to 7 1/2 but definitely a 6 1/2 or 7. There orth padding inside tobthey feel like ur walking on clouds
