How does the Tree Runner Go differ from the original Tree Runner?

It has a softer, more cushioned midsole, a reinforced toe for durability and a sleeker profile. The original is flatter and closer to barefoot.

Can I run or train in it?

No. It is a casual lifestyle sneaker with a knit upper and limited support, not a running or gym shoe.

Yes. The tree fiber knit is light and breathable, which owners cite as its main strength in warm conditions.

Allbirds knit sneakers are generally machine washable on a cold, gentle cycle and air dried. Check the care tag before washing.

Most buyers take their usual sneaker size. The knit upper is somewhat forgiving, but the reinforced toe can feel snug at first.

A lightweight tree fiber knit fabric, which is the breathable material Allbirds uses across its Tree line.
