Is the Xtratuf Ankle Deck Boot Ooto fully waterproof?

Yes. The rubber upper and sealed construction are built to keep water out, which is the point of a deck boot. It is not a Gore-Tex model, so it relies on the rubber rather than a breathable membrane.

How tall is the boot?

The shaft is about 6 inches, so it sits at the ankle. That keeps it easy to pull on but means it won't protect your lower leg in deep puddles.

What is the outsole made of?

Rubber. Xtratuf's deck boots are known for a grippy rubber sole aimed at wet, slippery surfaces like boat decks and docks.

What is the lining and insole?

The lining is a performance fabric and polyester blend, and the insole is synthetic foam. Expect a cushioned but not especially breathable feel.

Is this a men's or women's boot?

It is a women's model. Sizing follows women's US sizes.

How does it compare with a tall rain boot?

It is shorter, lighter and quicker to put on, which suits everyday wet-weather wear and deck use. A tall boot gives more coverage for deep water and mud.
