People Editorial Guidelines Updated on July 23, 2021 04:30 PM Share Tweet Pin Email Photo: Bauer-Griffin/GC Images It's no secret that we have immense admiration for Hollywood's leading ladies. (We write about them on a daily basis, after all.) But that certainly doesn't mean we don't also keep a keen eye on the industry's male heartthrobs — because we do — and in doing so, we noticed a key style similarity among a few resident hotties: Cariuma's sustainable sneakers. Cariuma is an eco-friendly sneaker brand that's blowing up right now, not only because of an ever-growing celeb backing that currently includes Jon Hamm, Robert Downey Jr., Pete Davidson, Chris Martin, Helen Mirren, Nina Agdal, and Whitney Port, but also because it's changing the footwear game for the better. Cariuma marries sustainability and style to create some darn good shoes that have, rightfully so, amassed crazy waitlists. Cariuma Buy It! IBI in Black Knit, $98; cariuma.com Specifically, it's the IBI sneaker — a vegan athletic shoe that was born from customers begging the brand to create a vegan style — that's continued to earn major buzz since its launch in 2019. Since then, over 20,000 people have put their names on the waitlist whenever it sells out (and it sells out all the time!), but the good news is that the IBI is still in stock right now — in fresh colors, too. But if the past is any indication, it'll sell out yet again. This IBI sneaker is the first of its kind, presumably one reason it can't seem to stay in stock for longer than a few days. It's crafted from a mix of self-regenerating bamboo (Cariuma is the first brand to turn bamboo into a high-performance shoe fabrication) and recycled plastic bottles — pretty darn cool, if you ask us. But these $98 athletic shoes aren't just easy on the environment, they're easy on the eyes, too. They feature a minimalist design with an on-trend platform-like sole that's, wait for it, made from recycled sugarcane.
