KUIU’s New HD Thermal Boot – Its Warmest Boot Ever
KUIU has brought out a new hunting boot for the coldest days this winter with the all-new HD Thermal Boot. This is a new set of boots built for sub-zero temperatures and extreme conditions, rated for below -50°F conditions. Built upon the proven HD Mud Boot, the new HD Thermal Boot uses a multi-layer hybrid insulation system. In a housing of a 6mm neoprene waterproof bootie, there is a layer of Solarcore aerogel foam that surrounds the foot, and a lofty synthetic insulation topped with a heat-reflective layer. A NASA-pioneered closed-cell foam, Solarcore, stays warm when wet and keeps its insulating power under compression. Additionally, a premium grid-fleece lining boosts warmth, comfort, and air circulation. Outside the boot is a vulcanized rubber overlay and EVA sole for added durability. The anti-slip central lugs deliver reliable traction on ice, and patent-pending tread sheds mud and snow so the boots stay light.
