Allbirds Superlight Series

The work of reversing climate change can feel heavy. Allbirds believes it doesn't have to be. Introducing: the SuperLight collection, two new styles that deliver a "light as a feather" feeling without compromising on cutting carbon.

The styles include a SuperLight Tree Runner and the SuperLight Wool Runner.

“We’re constantly working to deliver captivating and comfortable footwear while also reducing the carbon footprints of our products. We want to set the curve on sustainability and innovation. This reimagination of some of our core styles is the manifestation of that mindset,” said Tim Brown, co-Founder and co-CEO.

Both of the SuperLight shoes offers Allbirds’s signature comfort in a package that feels great for your feet and for the planet.

The SuperLight Wool Runner, for example, weighs in at just 4.23oz (W7) / 5.11oz (M9)... that’s lighter than an iPhone or a baseball. The carbon footprint of the SuperLight styles ranges between just 2.14 to 4.04 kg CO₂e – compared to the average sneaker carbon footprint of 14 kg CO₂e. Both of the styles are underpinned by Allbirds's newest midsole innovation: SuperLight Foam, their most lightweight and low-carbon foam to date.

SuperLight Foam is made with carbon negative, sugarcane-derived green EVA, creating a midsole that is approximately 70% bio-based content. (Compare that with usual industry foams that are often 100% plastics made from petroleum.)

SuperLight Foam is one of several super natural materials used in the collection. The SuperLight Tree Runner ($175 NZD) upper is made with lightweight, breathable FSC®-certified eucalyptus tree fibre. Compared to traditional materials, TENCEL™ Lyocell uses 95% less water than conventional cotton and has a carbon footprint that is one-third lower than virgin nylon.

While the SuperLight Wool Runner ($200 NZD) upper is made with ZQ-certified regenerative wool, aligning with Allbirds’s commitment to transition to all regenerative wool sources by 2025. Regenerative wool is produced on farms that exercise regenerative land management through practices like native plantings, ground clearing, and crop rotations.

“Cutting down on carbon is a game of inches. Every part of the shoe’s lifecycle is significant, from materials and packaging, to energy use and shipping,” said Jad Finck, VP of innovation. “Every component, feature, and detail of the SuperLight collection has been pored over to minimize carbon emissions without sacrificing on comfort and style.”
