Are the Moosonee boots fully waterproof?

Yes. They use a DRYFEET waterproof/breathable membrane, a gusseted tongue and a double Velcro gusset closure. That handles rain, slush and shallow snow, not standing water above the ankle.

Are they warm enough for winter?

The warm textile lining is made for cold everyday wear. They are not rated for extreme cold or long hours outdoors, so pair them with wool socks in hard freezes.

Do they fit true to size?

They are unisex and generally run true to size. If you wear thick winter socks or have wide feet, consider going up half a size.

Can I wear them for hiking?

They work for light trails and snowy sidewalks, but the synthetic outsole and canvas upper are not made for rough terrain or long hikes. Use proper hiking boots for that.

Wipe the canvas upper with a damp cloth and mild soap, then air dry away from direct heat. Do not machine wash them, since that can damage the membrane and lining.
