What the packaging might not tell you about the KEEN Greta

If you are already quite sold on the Greta, what with all its publicized features and female-specific engineering, great! That said, allow us to heighten your hype for it by presenting you the following:

Plushier backrest. Tired of stiffness bugging your heel and lower calf on your daily hikes? Well, “enough is enough,” says the Greta with its highly padded shaft. It also makes the collar more flexible, translating to less restrictive sideways movements.

Shield-like bumper. Another thing that you can prevent in the KEEN Greta is sustaining toe injuries. Indeed, like most KEEN hikers, this boot has a proprietary rubber toe cap designed specifically to absorb shock—ideal for haphazard and aggressive negotiations.

Cozy footbed. It traps in heat just like the boot’s insulated upper. On top of that, the footbed in question has odor control, leaving your tootsie not just warm but also stink-free.

Additional info

  • There exists a Greta Tall—the featured boot’s big sister, which sports a “taller” ankle cuff.
