I already know 2025 will go down in fashion history as the year of the Frankenshoe trend. Mash-ups of two popular styles combined in a single piece are everywhere I turn, whether on the sidewalks outside Marie Claire HQ or in the snaps of stars like Jennifer Lawrence (in Adidas), Kendall Jenner (in Uggs), and Hailey Bieber (also in Adidas) in Los Angeles. Ballet sneakers—hybrids of ballet flats and sporty trainers—ruled the first quarter. Now, a cross between a slipper and an outdoor slide will be the next inescapable shoe trend, since it just clinched Hailey Bieber's approval.
The model went for a smoothie run with husband Justin Bieber on April 9, dressed down in an oversize sage green hoodie and cut-off jorts. Mr. Bieber matched Hailey's laid-back energy with loose pants and a piece of his own tour merch. The couple both wore comfortable shoes for their sprint in and out of the shop: Justin chose rubber-soled clogs, while Hailey opted for olive green cloud slippers over equally plush socks.
