We’ve found, perhaps, the epitome of eco-conscious fashion. (You might want to sit down.)

A few weeks ago at the Amsterdam International Fashion Week, models walked basically naked down the runway, save for wearing biodegradable shoes. (The theme of the show was “Adam & Eve.”)

Shoe designer OAT won second place for their concept. The company claims its sneakers can be buried in the ground—the woods, a garden or a compost pile—and will eventually turn to dirt.

So, now when you are walking around town with these shoes on, know that you are:

• participating in low-carbon activity
• reducing congestion
• getting exercise
• and using shoes that don’t contribute to landfills!
