Comfort That Works Overtime
Whether you're putting in long winter days in the machine shop, on a road crew, or on the tarmac, cold and tired feet make it harder to concentrate on the task at hand. The Caliper is designed for jobsite comfort and safety. Feet stay warm and dry in frigid temperatures thanks to a Danner® Dry waterproof liner and 400g of Thinsulate™ insulation, with four layers of cushioning underfoot for comfort from clock-in to clock-out.
