Dr. Martens Slip resistant Oxford Shoes

Iconic Oxford Mr. Martens that are slip resistant for workers. They can also just be worn regularly for style! They have only been worn once, and they are in brand new condition despite minor creasing on the front top of the shoes. I bought these for my work. However, after only one day of wear, they are too big for me, which makes them difficult to walk in. Womens US size 9 Mens US size 8
