Allbirds founders Tim Brown and Joey Zwillinger created their best-known shoe—a minimalist merino wool runner—back in 2016, hoping to disrupt the synthetics-reliant sneaker industry. Since then, the certified B Corp has proven that sustainability sells: a November IPO valued the company at $4 billion, and it posted nearly $100 million in fourth-quarter sales (a 23% jump). A new design Allbirds recently launched in partnership with Adidas, meanwhile, releases less than a quarter of the greenhouse gases during production than a typical running shoe.
