If you're already familiar with Allbirds, you know the brand got its start making sneakers with sustainable materials. But did you know they also make sandals in the summertime? 

Allbirds recently released an ultra-squishy pair of slides that look extremely similar to the viral "pillow slides" that TikTok went nuts for a while back. In fact, after buying myself a pair of those pillow slides and writing a popular review about them, I knew I had to see how the Allbirds pair stacked up.

Not gonna lie, I think the strap makes them kind of ugly. I prefer the look of the pillow slides to the Allbirds. It's nice that these are adjustable, but they're definitely less sleek. 

True to its brand ethos, Allbirds uses its signature SweetFoam material, which is sustainably made from sugar cane. The straps are made with recycled polyester and renewable materials. 

I prefer neutrals, but you can get both of these pairs in various colors, from pastels to richer hues. Sally Kaplan/Insider

I got the "blizzard" color, but they're also available in black and bright orange. The Amazon ones come in about 15 colors. Both pairs fit true-to-size, and I'd size up if you're usually a half size.

The comfort is honestly unbeatable, and I can forgive the weird strap for how cloud-like they are to walk on — especially after a long workout or a day spent on my feet. They really feel like walking on gummy bears in the best way possible, and the insole is extremely bouncy, flexible, and cushy. 

Obviously, the price difference is pretty significant, but if that doesn't bother you and you're just after the most comfortable pair, the Allbirds win hands-down.
