Kim Kardashian was just spotted at LAX airport rocking Nike Air Yeezy IIs, designed by boyfriend Kanye West, with a black leather jacket, leather pants, and a black Céline bag. But Kim isn't the only fan; Rihanna also recently sported the same Nike sneakers while performing in London. Kanye has a deal with Nike to design one pair of sneakers every two years, and two versions of the Air Yeezy II — black/black solar red and wolf grey/pure platinum — launched on June 9. Then on June 12, Kim tweeted a photo of her and Kanye both wearing the sneakers in the black style. Although the limited-edition shoe retailed for $245 when it dropped, it's so hot that one pair is going for upwards of $1,500 on eBay. If you don't mind forking over that kind of money for shoes, then get in on one of the most talked-about sneakers to add sporty sass to all your outfits.
