Setup, Compatibility & Care
To maximize the lifespan and thermal efficiency of your Heat Holders, follow these care instructions: Wash them separately from delicate items, ideally inside out to protect the brushed fibers. Use a cool cycle (30-40 degrees Celsius) and avoid tumble drying, as excessive heat can damage the specialized yarn structure. Do not bleach, iron, or dry clean these socks, as these processes will break down the thermal insulation properties. They are compatible with most standard children's wellington and winter boots, provided there is enough space in the toe box to accommodate the thick cushioning.
