White Heeled Faux Leather Croc Boots

Beautiful brand new low top boots. Only selling because I’m unable to zip them up due to my legs being too big for them. Came with a little “mark” ( picture attached ), but you can’t really see it, and I think it’s something that can come off. Have been sitting in my closet, in the box for about two years and I just realized I never returned them. UK size shows 6 on the bottom but I’m size 8 in the US and this is the size I always get.
