Yeah! Its one of the weirdest hypebeast trends :D It all started couple months ago when Balenciaga created this blue bag ($2,145) which looked similar to 99-Cent Ikea Blue Bag.
Ikea quickly reacted on social media with some nice posts and now the hype is on. Ikea first did an official collabo with Nike - "Air Max 1 Fracta"
And now people make all kinds of custom IKEA sneakers, even Yeezy customs :D
