New💕Goodnight Macaroon OTK boots Marlo Tan | Sz 7.5 Selling these beauties! These are the Goodnight Macaroon super popular Marlo OTK boots! I love them but they are just a little snug for my me! These are size US 7.5 / UK 38. I'm a true 7.5 with a wider foot and the boot fit snug in the toe box with socks. I would suggest looking at the website for their size chart, but would fit a size 7 or 7.5 (narrow to medium foot) best. These OTK boots have never been worn. I just tried them on once.
