Ugg’s heel black lace up booties size 7.5

Ugg’s heel black lace up booties size 7.5 There is a slight abnormality on the left shoe on inside of outside and outside of outside of shoe (refer to pics & video) I have never noticed and these shoes were never worn outside so no idea from what this can be. Also a scratch on right heel. These are comfortable and warm and really cute. Thanks for looking :)
