Honestly? I got no idea.
K, as I always said I just need someone to prove me wrong ! Are there some special things you’d like to point out about demonia creepers? :) and for the black scratches: usually you can get rid of them easily with water and soap (and if its really hard then you can use nailpolish remover but you shouldn’t do that too often on the same spot.)
I once had Demonia ones in my hands and they were really light, so that’s a plus if you have a proplem with heavy shoes though I still got with recommending Underground creepers. I dislike T.U.K. because everytime I saw those irl they looked cheap and like they would fall apart soon.
I can only say what I personally think but I looooove creepers on skinny legs ! It puts accent on the shoes, I really like that.
And for prices, sorry but you got to look that up yourself, it depends on the brand and your location, postage and so on.
Good luck !
