Through eight generations over 200 years, Grubs has remained a family business dedicated to producing the most advanced outdoor footwear on the market. This dedication has led them to incorporate a number of innovative design features. Grubs boots come with Insta-Foam Ultra, a patented material that both insulates and waterproofs. They also provide extreme stretch to contour perfectly to the wearer’s foot and leg. A thick rubber exterior adds further shield against the elements, while moisture-wicking Airmesh inside the boot reduces sweat build up. For hiking, hunting, extreme winter activities and industrial work, these boots increase comfort, agility and overall performance.
