Ok, so my response on the other thread has given me the courage to write to the seller of these boots. Does this sound too harsh?
"Hi, I received these boots ok but they are not in the condition I expected based on the description of 'worn once' and the photos. The photos do not show the fact that the material is extensively damaged, cracked and peeling in several places, and that there is a spot of what seems to be purple nail polish on one toe. The boots are not in a wearable condition.
I am not sure how you would like to resolve the matter. "
