After review of product made by Allbirds, we are aware of which styles to avoid and which are worthwhile investments.

Allbirds Tree Flyer, $160

Learn more about the Allbirds Tree Flyers here.

As Allbirds’ first performance running sneaker created for long-distance running, the Tree Flyer is also Allbirds’ most technical design. It features a lightweight and airy upper made from eucalyptus tree fibers and a redesigned midsole using the brand’s new SwiftFoam material.

Made from a planet-friendly blend of natural and recycled materials, SwiftFoam is lightweight and bouncy, helping to return energy to the runner and eliminating the repeated harsh impact long-distance runners typically experience.

Despite having substantially more cushioning, the Tree Flyer is nearly 1 ounce lighter than the Tree Dasher 2.

Allbirds Trail Runner SWT, $140

Read our full review here.

As the name suggests, the Trail Runner SWT is Allbirds’ performance sneaker designed for trail running, hiking, and off-road activities. The design features a durable water-repellent upper, a sock-like fit to keep dirt and debris out, and durable outsoles with 4mm multi-directional treads for traction in all conditions.

Although the Trail Runner SWT is rugged and trail-ready, it’s still impressively lightweight, which makes it comfortable whether you’re using it for its intended purpose or for casual wearing.

In comparison to the Tree Dasher 2, the Trail Runner is only 2 ounces heavier. Overall, it’s still much lighter than most dedicated hiking or trail shoes.

Adizero x Allbirds Allbirds 2.94 kg CO2e, $120

Learn more about Adidas and Allbirds’ collaboration here.

Adidas and Allbirds first announced a collaborative partnership back in May 2020. Together, they were able to create a performance running with the lowest carbon footprint of any Adidas or Allbirds sneaker ever made.

After two sold-out launches of the original Futurecraft Footprint, Allbirds launched a new limited edition “Semi Turbo” colorway.

Now simply being called the Adizero x Allbirds  2.94 kg CO2e, the sneaker features multi-color Primegreen stitching accents and gum outsoles.

Allbirds Wool Runners, $110

Read our full Wool Runner review here.

Allbirds’ most famous silhouette is its wool runners. They’re comfortable, lightweight, breathable, and decently supportive. You can wear them with or without socks based on your preference (like all Allbirds shoes), but we’ve found that you may want to wash the insole frequently if you decide to repeatedly go sockless in the summer. It’s great that they’re machine-washable, too, but we’d recommend investing your $110 in a color that will hide some scuffs and dirt (read: not white).

Many Insider Reviews members have bought multiple Wool Runners, and we frequently gift them to friends and family. But, some team members would claim the company’s Tree Runners are even better.

Allbirds Wool Piper, $110

Read our full Wool Piper review here.

One popular critique amongst unconverted shoppers is that the original Runners aren’t their style. But, it’s hard to take issue with the Wool Piper — an Allbird-ized version of a classic cup sole sneaker.

The shoes are just as comfortable and low-maintenance as other pairs and use Allbirds’ typical sustainable materials (merino wool and SweetFoam soles), but the low tops are far more versatile. For this reason, the Wool Pipers may be our favorite pair yet.

In person, they’re comfortable out of the box — though one of us experienced some irritation after a full weekend spent in a brand-new pair. Over time, we expect them to loosen into a custom-fit like the Runners.

Allbirds Wool Loungers, $105

Read our full Wool Lounger review here.

The Wool Loungers are soft, breathable, and supportive — like a sturdier version of a house slipper. The body feels like one long, comfortable sock that moves seamlessly when you move, and the sole is sturdy but really lightweight. All in all, we love them for wearing indoors or as regular outdoor shoes.

After two years of wear, some of us ended up replacing worn-down insoles with new ones ($15) and noticed the upper has lost some of its shape as it has molded to our feet, but nothing too noticeable.

Allbirds Dasher, $135

Read our full Dasher review here.

Allbirds first-ever performance shoe, the Dasher, was a welcome surprise for us. It’s a great everyday running shoe, though you may wind up committing to a different men’s or women’s sneaker if you have specific needs or if you prefer a narrower base over stability.

The Dasher leverages all of Allbirds’ sustainable materials into one shoe: merino wool, SweetFoam soles, and a knit upper made from eucalyptus pulp. Its base provides better stability than many neutral pairs we’ve tried, while the knit upper allows the foot to move freely. However, while the knit also facilitates airflow, the Dashers are a smidge hotter than our personal favorite neutral sneakers.

The Dasher’s cushioning is perhaps its best feature. It’s more noticeable than a minimalist running shoe, but it’s not overly bulky or as heavily cushioned as Hoka One One. That combined with a wide platform that gives you solid stability on various terrains, and you’ve got a comfortable and secure ride almost anywhere.

Allbirds Tree Breezers, $100

Read our full Tree Breezer review here.

The Tree Breezers are, according to our review, “pretty much a dream come true” for lightweight, flexible, breathable flats that you’ll turn to day after day. They’re not as supportive as Allbirds’ sneakers, but they’re more padded than you may expect. They’ve also aged gracefully thanks to the structure of the Tree fabric, which holds its shape better than the wool styles.

Most of us wear them in summer as well as the fall, but one reporter found them to be too warm for the hotter months.

Out of the box, our testers ranged from feeling a slight rubbing on our ankles on day one (and none after) to zero pain or blisters out of the box on a 20-block walk. We all own more stylish pairs of flats, but we agree that we find ourselves favoring these due to their outsized comfort.

Allbirds Tree Runner, $105

Read our full Tree Runner review here.

Allbirds’ Tree collection is made from a sustainable, mesh-like textile that’s engineered with eucalyptus pulp, and the shoes are more cooling and breathable than the company’s other offerings as a result.

The Tree Runners are basically a breezier version of the Wool Runners, with a studier build that keeps its shape. They’re still incredibly comfortable and low-maintenance. We rely on them for the weekdays, weekends, and traveling, and many of us prefer the tree material to the wool since it seems to hold up for longer.

Allbirds Tree Skippers, $100

Read our full Tree Skipper review here.

We loved these shoes. They’re breathable, cooling, and have enough support for a full day of walking, standing, and dancing at music festivals or trekking around a new city as a tourist on vacation. They’re less restrictive and heat-trapping than sneakers for the summer, and we appreciated that we could tie the laces to keep them on as we run around or kick them off without untying them.

Allbirds Tree Toppers, from $74

Read our full Tree Topper review here.

We also really like Allbirds’ Tree Toppers. According to our full review, they have the same “light airiness of the Tree Runners, but [they’re] insulated enough to wear around on a drizzly November day in New York City.” They’re snug and supportive without being constrictive or bulky, and we didn’t notice any chafing when we wore them without socks.

They’re technically called high-tops, but they’re more accurately described as mid-tops.

Allbirds Mizzle, $125

Read our full Mizzle review here.

The main con of Allbirds is that you’d be out of luck if you stepped in a puddle in a pair of wool shoes. But not with its all-weather Mizzles. The Mizzles are covered in a water-resistant treatment that deflects raindrops, and the shoes have a reinforced sole that gives your feet a better grip on slippery surfaces.

Multiple testers noted that the Mizzles have become their go-to shoes for walking around on days with rainy weather thanks to the cozy merino wool and how lightweight they are in comparison to rain boots. A few testers found the fit to be slightly tight which wasn’t a dealbreaker but should be considered for anyone in between sizes or who loves super thick socks.

Allbirds Runner-Up Mizzle, $145

Read our full Runner-Up Mizzle review here.

Our team had mixed responses to this shoe, but we all agree that they’re effective at repelling water. Some testers describe the Runner-Up as their go-to footwear for walking around on rainy days, and others found them to be uncomfortable due to the bulky opening rubbing against their ankles. Some reviewers also found the shoes to be a bit tight in the vamp, throat, and toe cap, though adjusting the laces and breaking them in did create a bit more room.

Overall, we think they’re a good shoe that works well, but comfort will be case-by-case for each wearer.

Allbirds Wool Dasher Mizzle, $145

Read our full Wool Dasher Mizzle review here.

The Allbirds Dasher Mizzle ($145) is the same style as the Dasher performance shoe, but made from the brand’s merino wool and finished with a water-repellent finish. In other words, it’s designed to be a breathable, lightweight wool running shoe for all conditions.

The brand says the Mizzle Dasher should deliver the same technical functionality that we experienced with its original Dashers, but with the added convenience of being able to splash through puddles without concern. For added safety in wet conditions, the company also added a reflective logo to the heel for visibility and yarn into the laces for an extra strong hold.

Allbirds TrinoXO T-shirt, $48

Read our full TrinoXO T-shirt review here.

The Sea Tea, previously known as the TrinoXO T-shirt, is another blameless classic. It’s a basic T-shirt, but a very good basic T-shirt. The material, made partly from discarded snow crab shells, feels breezier, silkier, and stronger than cotton. If you’re only going to buy a few T-shirts and you love something airy with a boxy fit — or you can spend $48 comfortably — then we think you’ll like this.
