The Allbirds SuperLight Trainers are one of Allbirds’ first few cracks at building a training shoe with a low carbon footprint. This model boasts a lightweight construction and breathable upper construction.
As a fan of Allbirds shoes for daily wear, I was excited to see how their first training shoe would perform in the gym. This shoe is interesting, to say the least, and while I think there are some good traits with it there are also things that give me pause.
In my Allbirds SuperLight Trainers review, I’ll cover the pros and cons that come along with this shoe and discuss its performance in detail.
While I think there is a niche population that will enjoy the Allbirds SuperLight Trainers, I’m underwhelmed with their performance. From a sub-par fit to durability issues, these shoes haven’t been my favorites by any means.

Pros
- This shoe can be good for beginners that want a training shoe for casual HIIT and at-home workouts.
- If you love lightweight shoes, then you’ll enjoy how this shoe feels on the feet. It virtually feels like nothing with its weight.
- This model has a low carbon footprint and if your primary concern with your gear is its sustainability, then these may be a good option to explore.
Cons
- The durability of this shoe is sub-par. After just one training session, my pair had its toe box’s material start to lip and fray. I’m hoping this is an anomaly.
- This shoe’s width and upper volume are limiting so if you have wider and thicker feet you may want to steer clear of these.
- The lack of outsole tread will be a performance limter for these shoes in the contexts of serious training and outdoor workouts.
Who Should Buy the Allbirds SuperLight Trainers?
The Allbirds SuperLight Trainers will work best for anyone wanting a lightweight shoe for casual workouts. I think if one of your primary training shoes asks is having a model that feels like nothing on the feet then you’ll enjoy this shoe.
For context, my size 10 shoe has a weight of 5.25 oz which makes this model by far the lightest trainer I’ve ever worn. On top of this, I also think this shoe can work for those who primarily train at home or do more casual workouts.
If you’re newer to working out and only plan to do bodyweight exercises or light dumbbell and kettlebell sessions, then the stability of this shoe’s midsole should be plenty fine for your needs.
Regarding fit, this model will work well for anyone with narrower and low-volume feet. This shoe’s low-profile upper gives them a sock-like fit through the midfoot and for narrow feet, the toe box should feel good for your width asks.
Who Shouldn’t Buy the Allbirds SuperLight Trainers?
For any form of serious training, I’d suggest passing on this shoe. In the context of “serious”, I’m referencing those that want a shoe for lifting heavy, working out on different surfaces, or wanting durability for high-stress sessions.
This model’s lack of rubber outsole tread hinders its ability to grip surfaces like turf. On top of this, surfaces like concrete can wreak havoc on this shoe’s long-term midsole durability.
On top of this, I’m not convinced that this shoe’s upper durability will be the best-performing long-term. I’ll elaborate on this below in my performance section, but during a circuit of sled pushes and burpees the toe box overlay on my right shoe already started separating.
The last population that will want to steer clear of the Allbirds SuperLight Trainers is anyone with wider feet (EE or wider) and thicker feet. The midfoot’s upper volume can feel a little snug for this foot anatomy.

Allbirds SuperLight Trainers Pros
Over the course of my training and wear testing with the Allbirds SuperLight Trainers, I found a few things to enjoy about this model.
- One of the Lightest Shoes I’ve Trained In
- Good for Warm Climates and Casual Use
- Low Carbon Footprint
The first thing to like about the Allbirds SuperLight Trainers is its weight. This shoe definitely delivers on its weight and if you love lightweight training shoes then you’ll enjoy the feel of this model when training.
My size 10 shoe has a weight of about 5.25 oz which is pretty insane for a training shoe as most models weigh between 8.5 to 14 oz. If you want the lightest shoe possible for working out, then the weight of this shoe won’t disappoint.
The second thing to like about the SuperLight Trainers is their breathability and use for casual workouts. I can see these shoes being a great option for anyone living in warmer climates for the majority of the year.
The eucalyptus tree fiber and polyester upper breathes really well and if you want a shoe for working out on hot days or in hot classes, I could see this shoe being a really good fit for your needs.
This model also works decently well for casual training and if you’re not needing a model for heavy training, outdoor workouts on concrete, or tougher cross-training sessions then these shoes should be plenty fine for your workout asks.
The final thing to like about the SuperLight Trainers is that they deliver on their low carbon footprint claim. This shoe’s construction has a lot of recycled and sustainable materials and its carbon footprint comes in at 2.13kg CO2e.
Allbirds SuperLight Trainers Cons
I’ve found a few cons to keep in mind with the Allbirds SuperLight Trainers that I’ve found along the course of my testing and review process with these shoes.
- Long-Term Durability Can Be an Issue
- Outsole Isn’t the Most Grippy
- Lack of Width Limits the Fit Range
My first knock against the Allbirds SuperLight Trainers is their durability. I’m hoping that maybe my shoe is a one-off anomaly, but I’m not impressed by this shoe whatsoever regarding its durability for my investment.
For $120 USD, I would hope that a training shoe would last longer than a singular session. In my first workout, I performed a circuit with sled pushes, pulls, and burpees and I started to have the midsole pull away from the upper.
Mind you, this was only after about 15 reps of burpees. Sure, it’s an exercise where you’ll have more abrasion on a shoe’s upper, but it’s a bodyweight exercise and the material should last longer than 15 reps and a few sled pushes.
Another complaint that I have with the Allbirds SuperLight Trainers is their outsole construction. I get that Allbirds wanted to save on weight so they limited the rubber tread on this shoe, however, this comes at a performance cost.
If you regularly train on turf or wooden gym floors, then you may want to pass on this shoe. I was sliding all around in this shoe on turf and it’s not a model that I would want to go “all out” with during a training session for this reason.
This outsole construction will also be problematic for those that regularly train outdoors on concrete. The friction from concrete can cut into the midsole foam and create some fraying.
The lask knock that I have with the Allbirds Superlight Trainers is its lack of width and upper volume. For wide feet, pass on this shoe and consider something like the Nike Free Metcon 5 for HIIT (yes, this is a rare Nike shoe that has a wider build!).
I also noticed that the midfoot can feel a little low at times and if you have high arches or thick feet, you’ll want to consider this before investing in this shoe.
Performance Assessment
To break down the performance of the Allbirds SuperLight Trainers, I’ll discuss my experience with how these shoes perform for lifting, versatile training, short runs, and daily wear.
Testing the Allbirds SuperLight Trainers for Lifting
For lifting, the Allbirds SuperLight Trainers do an okay job if you’re keeping your training lighter. These shoes are marketed as shoes best for bodyweight and home workouts, so for these contexts, they’ll be fine.
If you’re using lighter dumbbells and kettlebells in your cross-training sessions, you’ll be set in this model. For example, their stability would be fine for something like a walking lunge with 50 lb dumbbells.
However, to test this model’s midsole stability with more dynamic lifting, I did perform a circuit with 70 lb dumbbell snatches with them, and their performance was just “okay”.
At this weight, I noticed the midsole compress and shift my weight forward a little bit, so I think if you’re going to lift in this model you’ll want to cap your loading in them and skip on barbell and machine work with them.
This — on top of this shoe’s lacking outsole grip — is also why I didn’t want to test these shoes for barbell and machine work. The potential risk of slipping wasn’t worth it, in my opinion.
Testing the Allbirds SuperLight Trainers for Versatile Training
For versatile training, this shoe works but at the end of the day, I thought it was kind of a letdown. I didn’t expect this shoe to perform the best for lifting, for example, however, for versatile training I had higher hopes for this shoe.
To start with the good, I like this shoe’s weight and how it feels sock-like on the feet. This will be a good training shoe for warmer climates and for those that like training barefoot in their shoes.
For things like box jumps, high knees, and jump rope, the weight of these shoes feels great. I also like how breathable this shoe’s upper is. The eucalyptus tree fiber breathes well and keeps these shoes cool when training.
My issues with this model for versatile training, and more specifically harder HIIT workouts, revolve around their lack of outsole grip and durability issues. The grip issue is a bummer because it limits the range in which you can use this shoe for versatile training.
The durability problem I ran into around the toe box is something that I think will happen to others, too (I hope not, though). The toe box’s upper isn’t reinforced the best and I’m curious if mine started peeling due to the stress from the sled pushes or burpees.
Testing the Allbirds SuperLight Trainers for Short Runs and Daily Wear
For short runs, I didn’t test this shoe for runs outside of a 1-mile warm-up and cooldown jog. I didn’t like the feel of these shoes for running and you’ll want to limit their use for treadmill running if you want them to last, in my opinion.
Outside of not enjoying their feel for running, I was also concerned with this shoe’s durability for running. If they had issues with the lighter demands of my cross-training session, I figured they’d be problematic for running, too.
In the context of daily wear, the Allbirds SuperLight Trainers will work best for those who live in warmer climates. For example, if you live somewhere like Miami, Florida, and you want a shoe for running errands, then going to work out these will work well.
My concerns with them for daily use are their lack of warmth for cooler months and their outsole durability and I’d also pass on using them in inclement weather. Mud and water could cause the midsole to break down faster.
My Experience In the Allbirds SuperLight Trainers SummaryAllbirds SuperLight Trainers Sizing
For the Allbirds SuperLight Trainers, I think you’ll be safe going true to size in them if you have a narrow to medium/neutral-width foot. Their length runs true and their width is biased towards medium-width feet.
I have a foot width that hovers around an “E” width and these shoes were okay if I went barefoot in them or wore thin no-show socks. However, if I wore socks with what I would call a normal thickness, they felt way too snug through the midfoot for me.
If you currently wear Allbirds and enjoy their fit, then you’ll likely be fine in these shoes, but for wider feet, you may want to tread lightly if you’re thinking about investing in these shoes.

Price Breakdown
For the Allbirds SuperLight Trainers, you can expect to pay $120 USD. This price point is similar to what you can expect to pay for other premium training shoes from big brands.
To be honest, I’m not the biggest fan of the price of this shoe. For a workout shoe costing over $100 USD, I want more durability and range with my training shoes.
My main issue is that I’m having trouble figuring out why anyone should pay that price for this model when there are stronger performers for the same price. For example, you can get the Nike Free Metcon 5 for the same price and it will perform circles around this shoe.
That said, if you love Allbirds and your main concern is your shoe’s weight and carbon footprint, then the price may make more sense for your needs. I don’t want my perception and poor experience with this shoe to completely deter you from investing in them and trying them for yourself if you really want to do so.

Takeaway Thoughts
Overall, the Allbirds SuperLight Trainers have been one of the bigger letdowns from shoes that I’ve tested lately. Going into this model, I had high hopes that it could be a good versatile option for anyone wanting a low-carbon footprint shoe.
While this shoe delivers on its carbon footprint promise, its performance doesn’t quite do the same. The sub-par outsole traction and upper durability give me pause with this shoe.
