Allbirds now makes water-resistant shoes - here's your first look, plus our verdict

  • You can't normally wear wool in the rain, which is too bad because we would love to wear our comfortable wool Allbirds sneakers all year long.
  • The company has a new solution: Its Wool Runner Mizzle ($115) and the Wool Runner-Up Mizzle ($135) are covered in a water-resistant treatment that makes raindrops slide right off.
  • They also feature a reinforced sole that gives your feet better grip on slippery surfaces.
  • These smart additions make an already great sneaker even more versatile. We tested them and thought they were just as comfortable and supportive as the original Runners.

"Will they or won't they?" I ask to myself as I crane my neck toward the gray clouds above me. As the seasons transition and weather forecasts shift with reckless abandon, it's becoming more difficult to tell whether it's going to rain later during the day.

That's not good news for your shoes, because if you end up wearing the wrong ones, your feet are trapped in the unholy embrace of wet socks. Even worse, you could also permanently ruin the material of your favorite pair of shoes. Advertisement

The new Mizzle collection features the Wool Runner Mizzle and the Wool Runner-Up Mizzle, which are both made with water-resistant merino wool and a reinforced sole for more traction on slippery surfaces.

The Runner Mizzle looks like the original Wool Runner, while the Runner-Up Mizzle is Allbirds' first high-top sneaker in wool (the Tree Toppers were the brand's first-ever high-top and are made from eucalyptus).

Allbirds differentiates these new sneakers from other water-resistant shoes on the market by emphasizing that it uses chemical-free, naturally derived materials to create its water-repellent treatment and water-resistant layer. The company as a whole is geared toward environmentally friendly practices, using materials like sustainably harvested eucalyptus pulp, recycled polyester made from plastic bottles, and carbon-negative EVA foam.Advertisement

We tried the new Allbirds Mizzles to test their comfort and claims of water resistance. Our testers include first-time Allbirds wearers and longtime fans.

Wool Runner Mizzle review:

allbirds mizzle 3


I own three different pairs of Allbirds (well, four now!), the original Wool Runners, the Tree Skippers, and the Tree Breezers. The Wool Runners are still my favorite and the pair I wear the most after two years, but I do have to admit it takes a certain bravery to put them on during cold weather season and risk getting them wet. The softness and coziness of wool is exactly why you'd want to wear them when it rains, which is why I love that Allbirds now has a water-resistant version. Advertisement

Since it didn't rain in the time I had to test the Wool Runner Mizzle, I couldn't test the claims of weather resistance directly. However, I did run them under the water of my faucet, with all the expected trepidation of anyone testing a waterproof or water-resistant product for the first time.

To my relief and happiness, the water slid right off (this effect was also very satisfying to watch). Some droplets stayed on the surface, but as I watched, they merely lingered there rather than absorb into the wool material. I tried ramping up the flow of the water, and the same thing happened, so I feel fairly confident about the material's performance in a real rain shower. -Connie Chen, reporter

I've somehow never worn Allbirds before trying out the Mizzle. So while I can't compare the new weather-resistant shoes to the original, I can confirm they are as cozy as I hoped wool shoes would be. I tried the Wool Runner Mizzle and immediately felt as if I had swaddled my feet in a soft, warm blanket.Advertisement

Wool Runner-Up Mizzle review:

allbirds mizzle 4


In my 10 months on the Insider Picks team there isn't a company that has received more praise from my colleagues than Allbirds. Anytime there's a new style or color released I know there's an email thread of excitement on its way. I wasn't sure if the shoes would live up to the hype, but after trying the Wool Runner-Up Mizzle I'm officially a convert. Advertisement

Beyond the fuzzy exterior that's also somehow water-resistant, the shoes are extremely comfortable right out of the box. The merino wool that lines the interior of the shoe provides a snug, blanket-like feel around my feet, and the bottom of the shoe is soft and squishy, but also supportive. The Runner-Up Mizzles are now my go-to shoe whenever I see a rainy day on my weather app. - Danny Bakst, content producer

I knew Allbirds was onto something when, during a meeting, one of the participants stopped me in mid-speech to tell me how awesome my Wool Runner-Up Mizzle looked. Indeed, it blends the cool high-top silhouette with the fuzzy wool exterior that Allbirds is known for.Advertisement

While I haven't had the opportunity to wear them long-term, there are some things that I noticed right away. Right out of the box, the Wool Runner-Up Mizzle slipped onto my feet easily and cushioned them with a soft feeling that's reminiscent of how my bedroom slippers feel.

But like my colleague Emily, I find some areas to be a bit tight, like the big toe and the top of the feet. My feet also feel like they were incubating, so I'd recommend wearing thinner socks to allow for some breathability (although wool absorbs moisture well) or save these for colder weather. However, I really enjoy the soft cushioning of the footbed and sole; I pounded the pavement for several hours and didn't find them uncomfortable, despite having not broken them in. - Les Shu, buying guides editor

The bottom line: Prepare for the rainy season with these new Allbirds sneakers.

The Mizzle is one collection of shoes you can wear out of the house with confidence, no matter how unpredictable the day's weather is. The Runners and Runner-Ups give you the lightweight, supportive comfort of a regular pair of sneakers, but the water-resistant benefits of a pair of bulky boots.Advertisement

If you have concerns about the fit and feel of a high-top sneaker around your ankles, we would recommend buying the The Runners instead of the Runner-Ups. Or, visit an Allbirds store near you to try on the sneakers in person.
