Some active models of Allbirds shoes, like the Runners and the Dashers, are considered a good pick for recreational joggers or weekend hikers. Still, they are generally not recommended for serious long-distance or off-road running. This is because they are heavier than most running shoes, with a build focused more on comfort than speed, and therefore don’t perform so great over long distances. Likewise, the treads on Allbirds Runners and Dashers are flat and smooth, so they’re more suited to paved surfaces and packed trails than muddy, slippery slopes.
