Why do you think Husk never wear's footwear?
do you think its a cat thing? or is it just due to his feet being being too big for shoes? or is it just a poverty thing? since he lost everything to Alastor years ago, maybe it is just personal preference but
he was once a human as well so I would think it would bother him that he's walking around barefoot outside in puddles and stuff? given it is hell so who knows what gross stuff he could be stepping in half the time lol.
not to mention standing out from other people and possibly feeding into his issues over people seeing him as an animal and not a human.
( yes I know its a minor detail that ultimatly dosn't matter but this is just how my mind works lol )
