When you buy a pair of AllBirds, whether wool runners, tree runners, or any other style from the brand really, you don’t necessarily need to wear socks if you don't want to. Indeed, even worn without socks, AllBirds are still some of the most comfortable shoes the market has to offer. However, if shoes worn without socks are not really your thing, the company has released a collection of Trino socks to match their shoes' comfort level, but you can, of course, wear Allbirds with your regular socks as well.
