The Gold Core lining has a three-fold benefit when used in dive boots. First, it’s super-slick, so donning is effortless. Second, its anti-microbial properties make this boot inhospitable to bacterial growth, which puts and end to unpleasant odors. Third, the Gold Core lining provides a great contact surface for your skin, reducing water transfer so your feet stay warmer. The boot’s exterior is highly durable and the top is armored with a vulcanized cap to absorb friction with dive fins. The Gold Zipper Boot is also outfitted with a durable zip and zipper lock.
