In the middle of winter, you can count on one thing: a surge in popularity for the warmest boots on the market. More often than not, that will include a pair of classic Ugg boots or slippers, but for 2021 I have a feeling that fans of the brand will want this celeb-approved update.

Joan Smalls has already worn Ugg's new Classic Ultra Mini Boots ($140), and now Kaia Gerber and Emily Ratajkowski have stepped out in the same pair—are we sensing a supermodel trend here? The new versions feature an even lower shaft compared to Mini Boots, which gives them a sleeker vibe. The lower design is especially great for mild fall weather when taller boots might be too sweaty, but you still want the coziness and comfort of shearling-lined shoes.

Scroll down to see how Kaia Gerber and Emily Ratajkowski wore the new Ugg boots.
