Not quite a Ballet drops and not exactly a sneaker: Meet the sneakerina.

As a mom in my 40s, one of the best parts of getting older has been caring less about what’s “in” and more about how things actually feel. Gone are the days of chasing trends and wearing heels that would give me blisters before dinner. And it seems Julia Roberts57, is right there with me.

The Oscar winner’s stylist recently Instagrammed a photo of Roberts swapping out red carpet heels for a pair of Vivaia Sneakerinassaying she slipped into them “for comfort.” She wore the same pair in Venice just a few weeks earlier, and more celebrities, including Oprahhave also been spotted wearing practical Vivaia shoes in other styles.

Vivaia Sneakerinas are washable, packable, and flexible (translation: You can toss them in a weekender bag, and they’ll still be your go-to for a coffee run or travel day). My co-worker tested them and said they felt “like wearing slippers,” and were so lightweight she had to check if she was still wearing shoes. A shopper at the brand’s website noted they felt “like walking on pillows” and that there’s “no need to break them in because they cradle your feet with pillowy, silky softness.”

Sure, $159 for a pair of shoes isn’t cheap, but because they cover so much ground (from work flats to travel sneakers to weekend walking shoes), they might actually save you money and closet space.

They’re also easy to dress up or down: Think cropped jeans and a blazer for casual Fridays, or a midi skirt and favorite tee for weekend errands. Roberts even wore hers with a designer dress, which tells you they’re versatile enough for a night out, too. One reviewer with ankle pain even ditched their date-night heels for them, calling them “the most beautiful and comfortable shoes ever.” Wear them with or without socks, and while the black pair truly goes with anything, there are 11 color options and even eight different laces so you can match your mood — and your outfit.
