Whether you have flat feet or just need a little more cushion, we started by adding extra high impact zone padding to our wicking, odor-resistant pad. And to guarantee your boots stay scent free, we utilize state of the art activated carbon technology. By setting the top high impact zone layer over our 4mm high density moldable foam, you'll barely notice the rockiest trails you follow. Imported.
