These are Allbirds SuperLight Tree Runner – an everyday sneaker best for walking or everyday wear made with an airy, breathable upper mesh-like material and foam sole for a barely-there feel, and light-as-air fit. It also has an integrated insole to reduce the amount of material used and puts your foot even closer to the cushioning. Sustainable and stylish— fashion meets function! These are pre-owned with plenty of life left. The condition is reflected in the photos with some discoloration and signs of wear present. Overall they still look very white and the bottoms show they were only worn a few times.
