Just in time for the holidays, Allbirds sneakers has blessedly brought back their incredibly popular (and adorably named) Smallbirds and we've already added to cart.

For the uninitiated, Allbirds calls themselves "The World's Most Comfortable Shoe," and TBH, that's not hyperbole. Founded in 2014, the simple and sustainable sneakers are not only internet famous, but the brand itself is a formidable leader in sustainable fashion.

Since the beginning, their mission was to create a line of shoes that's both wearable and eco-friendly. From the soles which are the first-ever made with the carbon-negative green EVA and laces made of recycled material to their minimal packaging they've created a brand and product that contributes to a better future for the little ones we're raising. And that's no small feet feat. (Sorry, I had to.)

The Smallbirds are a mini version of their best-selling design, the Wool Runner–a shoe that's loved by celebrities, Silicon Valley titans and busy moms just like you and me. They're made made from breathable and no itch Merino wool that keeps feet cool in the summer and warm in the winter. And because of the design, they can easily be worn with or without socks without getting stinky. But most importantly, they are machine washable so messy kiddos–and, let's be honest, messy mamas–don't have to worry about trashing them in just a matter of weeks. We've even handed down pairs that look brand new from one kid to the next.

A walk through their reviews shows you how much these shoes are loved by every single person who slides them on, with the word "comfort" repeated over and over again.

So why not give that level of comfort to your favorite tiny feet in the world? They sell out each and every time they release them, so don't wait! This run offers four neutral colors, two in their regular wool and two in a totally cozy and irresistible fluff wool.
