When I saw that these are made of merino wool, my first thought was: [insert monocle-eye WTF emoji here]. But then I thought about it, and realized wool is one of humanity’s secret weapon fabrics—antimicrobial aaaaand warm aaaaaand soft. Plus, of course sheep run through their misty emerald fields! Why wouldn’t it make the ideal running shoe fabric? “They market them as ‘the world’s most comfortable shoe’ and I have to agree,” says SwearBy founder Kate Foster Lengyel. A whopping 13 SwearBy editors have raved about them as of press time, and we think Shireen Shakouri put it best. “When they told me it’d be like stepping on clouds, I figured it was an exaggeration. It wasn’t!” When the soles are made from a carbon negative Brazilian sugarcane foam, it’s not just cloud-like—it’s angelic.

Whoops!
