Grundens Deviation Thermo Tall Boot Brown is a tall thermal boot designed for versatile use both on the boat and in the outdoors. The shaft extends above the calf for comprehensive protection, while the fully waterproof construction keeps feet dry.
The boot features a 38.1 cm (15-inch) shaft with flexible neoprene panels that make it easier to put on. A thick, cushioning insole enhances comfort and helps absorb impacts. The compression-molded EVA midsole supports the foot and adds further cushioning.
HeiQ Pure and SmartTemp lining technologies support wearing comfort. HeiQ SmartTemp is a thermoregulating finish that helps balance the internal temperature of the boot during use.
Grip-patterned rubber lugs along the edges of the outsole provide improved traction on loose terrain, while the central lugs enhance grip on wet surfaces. The non-marking rubber outsole features a grippy tread pattern and finely siped central lugs that support stable footing on varied surfaces.
