NWOT Allbirds Black Tree Flyer Sneakers Women’s Size 6

Shoes are brand new never worn. I just don’t have the box - Breathable uppers are made from a eucalyptus tree blend material and help keep the air flowing for added comfort - Compared to traditional materials like oil-based polyester or nylon, using tree fiber cuts the shoes' carbon footprint in half - 48% bio-based SwiftFoam™ midsoles are lightweight and bouncy; an innovative low-heat foaming process means the production of these midsoles requires less energy - External heel counters are made entirely of scraps from the SwiftFoam midsole production process - Heel counters and flared, geometric midsoles help keep your feet steady - Outsoles are engineered to flex, helping to smooth out heel-to-toe transitions and increase energy return - Natural rubber tread on outsoles has a zonal traction pattern that gives you a strong foothold on pavement - Easy to wash: simply remove the laces and insoles, and place in a delicates bag (a pillowcase works too), then choose a gentle cycle with cold water and mild detergent - To dry, shake out any excess water and set aside to air dry; the shoes will regain their original shape after 1 or 2 wears - Don't put the shoes in the dryer; you can hand wash your laces and insoles separately Technical Specs Upper TENCEL lyocell (eucalyptus tree fiber) Gender Women's Lining ZQ-certified merino wool heel lining Midsole SwiftFoam made with bio-based Pebax Outsole Natural rubber Best Use Casual Footwear Height Ankle Footwear Closure Lace-up
