A Roomier Version of the Classic We've redesigned our iconic Chore boot with an adjustable, waterproof gusset for the perfect fit around the calf. Handcrafted from natural rubber, the Chore Wide Calf adjusts to the unique contours of your foot, making these reliable work boots flexible, 100% waterproof and lightweight. These tough boots feature a rubber overlay and quick cleaning sole, allowing you more time to get on with the important stuff. The upper is reinforced in both the toe and heel area, plus additional arch support giving you the protection you need. The 5mm neoprene makes these boots lightweight and flexible, with breathable air mesh lining to keep you cool on warmer days.
