The shoes in question, adapted from a previous model Lup made for actors, are a European size 75 and require almost one square metre of leather.
Lup has since received five orders for the $115 shoes, which take him two days to make.
On social media, the unique shoes have been met with amusement, with many comparing them to flippers.
"This is brilliant and absurd,” one person tweeted, while another said the shoes "seem like scuba fins."
