Jennifer Garner is one of many celebs crushing on these comfy Allbirds sneakers

No celebrity does relatable fashion quite like Jennifer Garner. The actress is our go-to source for finding everything from cozy sweaters to flattering jeans and comfortable sneakers. One of her faves, Allbirds Wool Runners, are also loved by several other Hollywood A-listers, including Mila Kunis, Cindy Crawford and even Jennifer's ex-husband Ben Affleck. (Yes, the comfy kicks come in a men’s version too.)

Jennifer has been spotted in the Allbirds sneakers several times over the years, and it’s easy to see why she is such a fan. The comfy sneakers boast the world’s first carbon-negative green EVA midsoles (made from Brazilian sugarcane), a cushioned insole (made from castor bean oil) and a moisture-wicking and odor-reducing upper (made from ZQ Merino wool). Even the laces are sustainable — they're made from 100% post-consumer recycled polyester. Essentially, one old plastic bottle becomes one pair of shoelaces.

Along with being soft and cozy against the skin, the wool upper is also thermoregulating, so your feet won’t overheat while wearing them. And perhaps best of all, the shoes are machine-washable. That’s right, you can throw these bad boys in the wash if they ever get dirty!

The lightweight sneakers are not only loved by celebrities: Nearly 5,000 shoppers are fans too. One said it was “love at first step” before adding, “Comfy, gorgeous color, attention-getting. Just wonderful. As someone with ‘bad feet,’ I have a very hard time with comfort issues (wide width, my orthotics must fit into the shoe...). Wearing these shoes is akin to wearing house shoes that look good everywhere.”

Another raved, “These shoes are so comfortable. Can be worn with or without socks. Dirt brushes off easily. Bought them for a trip to Scotland and can't wait to wear them there.”

The sneakers range in size from 5 to 11. Unfortunately, they don’t come in half sizes, but Allbirds recommends sizing up if you are in between. Choose from nine stylish colors directly on the Allbirds website, or at Nordstrom or REI. Between Jennifer’s seal of approval and the thousands of five-star ratings, these comfy kicks deserve a spot in your rotation this season. Snag a pair for yourself!
