men Allbirds Tree Runners Gray Shoes 10

A breezier take on our original Wool Runner, with a lower profile than the Tree Runner NZ, this fan favorite is a versatile, do-it-all pick for wearing just about anywhere. A light, breathable upper hugs your foot, while a Merino wool-blend lining provides all-day comfort—socks optional. 

Thoughtfully designed

• Breathable tree knit upper for a light, cool feel
• Sugarcane-based SweetFoam® cushioning with responsive energy return
• Soft, Merino-wool blend lining
• 100% recycled polyester laces sourced from plastic bottles
