Is the Keen Zionic ADV waterproof?

No. It has no Gore-Tex or other waterproof membrane, so it is best for dry trails and warm weather. Water crosses the mesh upper quickly in rain or wet grass.

How does the quick lacing work?

A single pull cord tightens the upper, and a small cord lock holds it. You adjust tension by pulling or loosening the cord rather than tying laces.

What is the shoe best suited for?

Day hikes, fast trail walks and travel where you want one light pair. It is not the right pick for heavy packs, wet climates or rough off-trail scrambling.

Does it come in wide sizes?

No. The Zionic ADV is listed in normal width only, so hikers who need a wide fit should look at other Keen models.

What is the upper and lining made of?

The upper mixes textile, mesh and synthetic overlays, and the lining is mesh. That keeps it breathable but not water resistant.

How does it compare with a waterproof hiking shoe?

It is lighter and more breathable than most waterproof shoes, but it gives up rain protection. Choose it for dry conditions and a waterproof model for wet ones.
