Are the UGG Adirondack Tall XXV boots actually waterproof?

Yes. They use a waterproof leather and suede upper with a waterproof membrane bootie and gusseted design, and buyers report dry feet in snow and slush.

How cold can I wear them?

UGG rates them to -32°C with 3M Xerogel insulation, a 17mm UGGplush wool-blend lining and sockliner.

Many buyers say sizing was as expected, but some report they run big and wide. If you are between sizes or have narrow feet, consider sizing down.

The shaft is about 12 inches with a roughly 20-inch circumference, and the cuff can be folded down.
