Description

Designed to put a spring in your step, the men's Allbirds Tree Flyer sneakers are lightweight, responsive and wildly comfortable when you're out for a stroll or running errands around town.

Features

• 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
