About Atoms Shoes

Atoms shoes is a New-York based sneaker brand solving the problem of poorly fitting shoes. The brand offers quarter and half sizes and allows customers to buy pairs of shoes in two different sizes for different sized feet.

Atoms was founded by husband and wife duo Sidra Qasim and Waqas Ali. Shoemaking craftsmen inspired Sidra in a small village in Pakistan, and this is where her passion for shoemaking began. Sidra learned from these craftsmen and collaborated to launch a small Collection called Hometown in 2012.

A few years later, and thanks to a Kickstarter campaign and acceptance into a San Fransisco accelerator program called Y-combinator, Atoms was launched, and the goal to create the world’s most comfortable shoe was born.

About Allbirds

Allbirds is a sustainable shoe company creating sneakers, running shoes, and flats from eco-friendly materials and sustainable practices.

Allbirds founders Tim Brown and Joey Zwillinger

Allbirds was launched in 2014 by New Zealand-native Tim Brown and San Francisco-based Joey Zwillinger, both with a passion for sustainability.

Having grown up in New Zealand, Tim wondered why merino-wool – a sustainable resource with moisture-wicking properties – was virtually absent in the footwear industry. So this is where the journey began, and the Allbirds Merino Wool Runner was born.

Until the Wool runner launched, many sustainable sneakers were un-stylish and lacked key features you expect from sneakers, including a comfortable sole and breathable fabric. It was here that Allbirds set the standard for other sustainable shoe brands to follow.

Allbirds produce a range of high-quality men’s, women’s, and children’s sneakers, running shoes, and flats, all from sustainable materials.

Tree Fibers

Harvested responsibly from FSC® certified forests, Allbirds produce Eucalyptus tree fibers which are then spun into silky smooth and breathable yarn and knit into its classic tree runner and dasher styles.

Merino Wool

Responsibly sourced ZQ Merino wool from New Zealand is used for Allbirds Wool Runner and Wool Mizzles styles. The ZQ organization ensures the wool sourced meets high farming, land management, and animal welfare standards.

By using Merino wool, Allbirds uses 60% less energy compared to typical synthetic material.


Recycled Plastic Bottles

One recycled plastic bottle is transformed into Allbirds’ signature shoelaces.


Allbirds Sweetfoam® soles are created from responsibly sourced sugarcane, a renewable resource that grows quickly, removes carbon from the atmosphere, and requires little irrigation.

No, Atoms shoes aren’t waterproof. The upper material is breathable, which prevents feet from sweating; however, it won’t keep the rain out.

Are Allbirds shoes waterproof?

One drawback for Allbirds shoes is that they don’t produce a fully waterproof sneaker. However, water-resistant styles are available that form part of the Mizzles range.

Is Atoms Sustainable?

Atoms shoes are working on setting up a recycling program for its shoes which are 99% recyclable. In addition, the brand uses water less dyeing process to eliminate toxic runoff, and Atoms offsets the carbon on all shipments.

However, we wouldn’t consider Atoms Shoes a sustainable brand. The company doesn’t use sustainable materials and opts to use virgin polyester to create its shoes. In addition, the brand doesn’t provide any information on the working conditions of its factory in Busan, South Korea.
