GIVENCHY shark boots knee high

Size 42(12) worn for maybe 30mins, which was from my house to my car, after a few mins of wearing found out the hard way that Shoe is very very slim, so if you’re not familiar with this type of boot. Should go try on first. I have all the packaging, tags and most importantly receipt. Can post once I’m back home(out of town) original price 2650 after taxes.
