Why we love it

A running shoe is a personality. A dress shoe is a meeting. The Tree Runner is the third thing: a knit sneaker light enough for the errand and plain enough that nobody asks what it is for. Allbirds makes the upper from tree fiber, which is their way of saying it feels cool and it can meet a washing machine.

We love the Jet Black pair with the black sole because it looks like a shoe you meant, not a wool experiment that escaped a catalog. The midsole is the bouncy sugarcane one. The listing is machine washable, which is the feature that matters the week the shoes meet a puddle and a train. Whole sizes only. This page is men’s 11, Medium width. When we looked, it was $100, in stock, ships from Amazon, sold by Allbirds Shoes.

It will not replace a trail shoe or a boot with a welt. It will be the pair you put on when the day is mostly walking and you would like the shoes to rinse. The foam clog can keep the garden. This one keeps the sidewalk.

The longer story

This is the Allbirds Men’s Tree Runner in Jet Black (Black Sole), men’s size 11 Medium. The listing’s notes: a breathable everyday sneaker with a flexible upper made from lightweight natural tree fiber, a bouncy midsole made from sugarcane, and a machine-washable build. Whole sizes only. If you are between sizes or you have wide feet, Allbirds says to size up. The brand’s own line on the page includes the carbon-neutral and B Corp notes. This link is that color and that size, not a different swatch.

Good for

  • Long days on your feet, errands, and the commute that is mostly walking
  • Anyone who wants one black sneaker that can go in the wash
  • A gift, if you know they wear a men’s 11 Medium. Guessing a shoe size is how returns happen

Skip it if

  • You need a different size or a white sole. This page is Jet Black, black sole, men’s 11 Medium. Changing the swatch changes the listing
  • You wanted a trail runner, a waterproof boot, or a shoe with a carbon plate. This is an everyday knit sneaker
  • You are between sizes and refuse to size up. The Tree Runner comes in whole sizes, and the brand’s tip is to go up

When we looked, it was $100 and in stock. The deal link is the Amazon page (/dp/B0CTS187BN) with our Amazon Associates tag threepaths-20. Confirm the color says Jet Black (Black Sole) and the size says 11 Medium before you check out.
