Is the Keen Anchorage III actually waterproof?

Yes. It uses a KEEN.DRY membrane, which is Keen's own waterproof, breathable liner. It keeps slush and wet snow out while letting some moisture escape.

How cold can I wear it?

It has 200g of KEEN.WARM insulation, which suits cold winter days and short outings. For extended time in deep cold or standing still, a heavier insulated boot is a better fit.

Does it run true to size?

Keen boots generally run true to size, and this slip-on is roomy through the forefoot. If you are between sizes or have narrow feet, consider sizing down for a snugger fit.

Can I wear it in deep snow?

It handles packed snow, slush and plowed sidewalks well. The shaft is low, so deep drifts can get in over the top; a taller boot is better for that.

What is the difference from the Anchorage II?

The Anchorage III keeps the slip-on build and waterproofing but updates the upper and sole. It is the current version, so replacement parts and the latest fit are easier to find.
