A patented polymer cross-linked into every OrthoLite® foam resists microbe growth and provides protection from fungus, bacteria, and odor. This lightweight foam enhances performance and day-to-day comfort. Unlike traditional foam technologies, the compression set of OrthoLite® foam is less than 5%, so the fit and cushioning of your Justin Just Dry™ insoles will never change. These insoles are eco-conscious, as the OrthoLite® foam contains 5% recycled rubber. Justin Just Dry™ insoles are machine washable and will come out like new every time and maintain all of the performance benefits after washing. This unisex style is designed to fit most Justin round toe boots.
