Featuring a breathable TENCEL Lyocell upper, castor oil and sugarcane foam, and recycled water bottle shoe laces, the Tree Runner is as sustainable as (new) shoes get. Flexible and soft, these shoes feel comfortable and lightweight during long days on your feet (i.e., traveling, errands, etc.)
According to Nelya Lobkova, Surgical Podiatrist, founder of Step Up Footcare, and biomechanics consultant for KLAW, Allbirds’ upper wool blend can be especially comfortable for those with forefoot deformities, such as bunions and hammertoes.
However, Lobkova notes that Allbirds are relatively unsupportive. If this is an important factor for you, we recommend swapping out the removable insole for a custom orthotic.
In a comparison of Allbirds to Cariuma, mindbodygreen contributing writer Jamey Powell wrote, “I’ve known about these shoes for so long and can’t believe I’ve been sleeping on them. They’re truly so comfortable and great for walking the dog, running errands, or just bopping around town.”
