These are based on the MSCHF "Big Red Boots"
They are, no word of a lie, supposed to look like Astro Boy's shoes
MSCHF are an art collective that do deliberately wacky stuff. They basically have a website where they'll do extremely limited "drops" that sell out within minutes. They'd do weird shit like "Puff the squeaky chicken", a bong that's also a rubber squeaky chicken:
(it really does squeak) or "Sacred Seltzer", which was basically White Claw but legitimately made with Holy Water:
and they've done over stuff too, like paintings of people's medical bills which they then sold at a high enough price point to pay off those people's medical bills, or a robot that wrote your messages in child's handwriting and sent them to senators. They even bought one of Damien Hurst's dot paintings and cut it up and sold the dots:
and they bought one of the Boston Dynamic dogs and mounted a paintbull gun on it and let people control it in a little art gallery they'd set up:
Mostly they're taking the piss out of consumerist trends and more widely capitalism (they had one drop that was basically just hardware from a variety of failed mid 2010s venture capital funded startups) and you can make your own mind up on whether or not this is good art, but for whatever reason they started getting into sneakers (probably to mock sneakerheads who spend loads of money on sneakers and then just display them). They're the people behind Lil Nas X's "satan sneakers" that contained human blood
and they've also done stuff like medical boot shoes:
But yeah, for whatever reason, they've started selling actual sneakers, and they do stupid brand collabs as a joke. In this case this is a legitimate collab between MSCHF and Crocs. The thing is though, hypebeasts are now starting to treat MSCHF stuff as desireable fashion instead of deliberately stupid looking art pieces;
and I reckon Victoria Beckham doesn't really "get" what's going on with the boots, she just thinks they're "on trend". I guess if enough people misunderstand the reasoning behind those boots and start wearing them (or knock off dupes) then they actually are on trend. Basically the only guy who gets it is the model they used to announce the Big Red Boots x Crocs collab
