Allbirds Women’s Tree Flyer Running Shoes

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 These are in great condition and SO comfortable!! Awesome running, walking, or travel shoes. Bought them on a trip to London (hence the £150 sticker), and they were amazing for all the walking we did, but I just don’t reach for them anymore. I typically wear a 10 but went with a 10.5 in these to get a little extra room in the toe box.
