The Ocean Pro 5mm Dive Boot is perfect for diving all year round due to it being 5mm, this will keep your feet warm in winter and still give you protection in the warmer months. This particular boot has glued and stitched seams which means it is super durable and will last many years, with care of course. When ever you are diving with an open heel fin, a dive boot is necessary as without this, you will encounter blisters, cuts and abrasions. The rubber protection that runs up the top boot stops the fin from rubbing on the boot and wearing it out, so this is a great feature, as well as the corrosion proof zipper.
