  “Are Allbirds comfortable? In short, extremely. The sole of an Allbirds shoe is made from a proprietary low-density foam that contributes to the shoe’s extremely lightweight feel, its main distinguisher from other typical sneakers.”
• The World Pursuit
  “It was like I’d bought slippers in runner form. They are a breeze when traveling through airport security and are super comfy on and off the planes. They are ultra-light and pack up small making them the easiest travel shoes ever.”

  “Overall, [Allbirds] offerings are breathable, lightweight, low-maintenance, and unapologetically comfortable.”
• USA Today
  “The Allbirds are so comfortable, I could sleep in them if it were socially acceptable to wear shoes in bed. The shoe fits snugly against your foot with a tapered toe for an elegant, elongated look. The sole is raised near the heel, which is fantastic for arch support.”
• Travel & Leisure
  “Thankfully, they held up. From my flight from Los Angeles to Honolulu to running through the hills in Lanai and hikes in Oahu, they provided the ultimate comfort. They felt cushioned on my feet, keeping a bounce in my step as I jogged up hills tucked into the center of the island.”
• U.S. News and World Report
  U.S. News senior travel editor Nicola Wood says. "I've worn them through multiple airports and to tour around big cities all day. They are like walking on a cloud and I never have any foot pain! You can wear them with or without socks, and they are machine washable which is the cherry on top."

Comfortable shoes should have three things: good fit, great cushioning, and be made with breathable materials. 

Allbirds takes these basic goals and turns it up a notch. Allbirds is obsessed with creating comfortable shoes and apparel using renewable materials like wool, sugarcane, tree fibers, and castor bean oil—always keeping you and the planet top of mind. 

Lace up (or slip on) your Allbirds and experience how sweet sugarcane can feel. Yep, our SweetFoam® and SwiftFoam™ midsole are made with sugarcane and optimized for cushion, stability and energy return. 

In fact, using sugar cane as a raw material is so self-sufficient, that when it’s processed, its biomass is extracted to power the mill itself and fertilize the next year’s crop. That’s some hard-working stuff!

Our removable castor bean sock liner emits less carbon than petroleum-based foam and is contoured to provide flexible, anatomical support.

Not only do materials matter for comfort and breathability, they matter to the planet. Allbirds uses sustainable materials so that our customers can be kind to the Earth while being kind to their feet. 

From the merino wool and eucalyptus tree fiber in many of our uppers, right down to shoelaces made with recycled materials, we’re aiming to replace petroleum-based synthetic materials with natural alternatives. The side benefit to that? Our shoes are more breathable and more comfortable—so you can enjoy every step.
