Superior Insoles for Superior Support Kg's Cushioned Insoles are made with a polyurethane and memory foam cushion, designed to act as an impact absorber that easily transforms your everyday work boots, making them more comfortable, supportive, and better for your feet. These heavy duty insoles are soft, comfortable, and flexible without being too firm, providing you with lasting, good arch support that not only acts as a pain reliever for those on their feet all day, but offers more sustained energy by absorbing the impact of every step you take. This can help prevent fatigue, foot injury, and flat foot related to consistently using poor footwear. Our work insoles are designed for mens work boots for those in industrial working environments. Plus, with Intellifresh technology, you'll have the added benefit of an odor neutralizer and smell eliminator! High-Quality Products Proudly Made in the U.S.A.
