Kendall Jenner and Kylie Jenner Both Posted Images Wearing Yeezy Boost 350s

Next up: one of the Kardashian sisters.

After years of endorsing competitive sneaker brands, the Kardashian-Jenner-Wests have formally joined team Adidas.

Kanye West started the trend, when he partnered with Adidas to create his fashion label Yeezy in 2015. A few years later, Kendall Jenner became an official brand ambassador. Kylie Jenner, who has previously appeared in campaigns for Puma, became the most recent to partner with Adidas when she reportedly inked a deal with the company in August.

Last night, Kylie demonstrated her commitment to Adidas and West by posting an image of herself wearing a pair of sneakers from West’s collection. She captioned the image, “Just got my Yeezy Boost 350 V2 Triple White.”

Today, her supermodel older sister, Kendall Jenner, joined the campaign as well, sharing an image promoting her own pair of Yeezy Boost 350 V2 Tripe White sneakers. In a rare turn of events, Kendall chose a more revealing ensemble than Kylie. While Kylie wore a skin-tight white mini dress for her post, Kendall paired her sneakers with a boxy gray T-shirt and super high-cut Calvin Klein underwear. (Both Kendall and Kylie have appeared in Calvin Klein campaigns as well. In fact, the series of five photos that the model shared on Instagram could just as easily be an ad for the American fashion house as it could for their brother-in-law’s new sneakers.)

Next up: one of the Kardashian sisters, as the Jenners have already started the Yeezy promotion ball rolling!
