These sneakers marry features that popularized the original Tree Runners (like a sustainable, breathable blend of recycled materials) but scale it up with socklike comfort. Our tester noted that they required zero breaking-in time, adding that they were "slipper-like" from the jump.

The minimal Tree Gliders pair well with everything from tailored trousers to gym clothes. Made with the lightweight design Allbirds is famous for, these shoes help put a little spring in your step.
