With over 358 million views on TikTok and countless appearances on A-list celebs and mega-influencers, cloud slides have officially staked their claim as one of the biggest footwear trends of the early 2020s. And as someone who happens to have her toes in a pair right this very minute, I understand why these comfort-driven “ugly shoes” are here to stay. And why they’ve sold like hotcakes during Amazon’s Prime Day sale, which ends today, July 12, so you’ll need to act fast!

Peak-pandemic, I purchased a pair of classic cloud slides on Amazon to wear while I worked from home. And now, here I am, years later, still wearing them while I work from home because they’re that comfortable. Most cloud slides are made from EVA foam, a lightweight, rubbery material that makes them shock-absorbent and incredibly supportive. The best feature slip-resistant bottoms for added safety and arch support for comfort.

Plus, pillow slides can be worn in the water, making them an excellent footwear option for the pool, the beach, the backyard, or communal showers at the gym. Cleaning your shoes is surprisingly easy, too. Simply wipe them clean with a damp cloth, and voilà! I also use a magic eraser every so often to remove stubborn dirt and scuff marks.

TikTokers can’t stop raving about the affordable cloud slides they scored on Amazon, either—especially Prime Members who got theirs delivered to their door via free two-day shipping. Reviewers say wearing them is like “walking on marshmallows” and that “the soft padding makes them a pleasure to wear, even on long walks or extended periods of standing.”

Another key signal that TikTok’s so-called pillow slides are evolving into a widespread puffy sandals trend: The ever-increasing number of silhouettes, color options, and designer cloud slides available. While Yeezy slides may have kick-started the trend way back when, everyone from Loewe to Fendi, Prada, Gucci, and Bottega Veneta have dropped versions of their own over the past year. And sightings on It Girls like Hailey Bieber, Lori Harvey, Lucy Hale, Dua Lipa, and the Kar-Jenner clan certainly haven’t hurt the shoe’s popularity either.

This year’s Amazon Prime Day deals on cloud slides offer the perfect opportunity to dip your toe into the trend. If the OG cloud slide silhouette—which features a wide top strap and a pillowy platform sole—isn’t quite your style, try a pair with thong straps or adjustable buckles. Heck, when the prices are this good, why not grab a few different styles to see which ones you like the most? The sale ends tonight, so you’d best get a move on it!
