Aqualung 7mm Echozip Dive Boot Black / Blue

As a general rule, thicker neoprene insulates more, so colder water pushes you toward thicker accessories, but fit, dive length, and personal cold tolerance matter as much as the millimeter number. Divers commonly lose a great deal of heat through the head, so a hood is often the highest-value warmth upgrade for the money. Remember that every added piece of neoprene also adds buoyancy you will need to account for.

Boots should fit like a snug athletic shoe, with no heel lift and no crushed toes; a little water inside is normal, a sloshing pocket is not. Try them on with the socks you would actually dive, and remember your fin foot pocket has to accommodate the boot. Hard-sole boots protect on rocky shore entries, while soft-sole boots are lighter and pack smaller for boat and travel diving.

Gloves should be snug across the palm with fingertips reaching the ends without bunching, since trapped air and loose fingertips destroy dexterity. Thicker gloves are warmer but make buckles, clips, and inflator buttons harder to operate, so choose the thinnest glove that keeps you comfortable in your conditions. Try working a clip or buckle while wearing them before you commit.

A hood should seal around the face and neck without restricting your throat or jaw, and lie flat on your head without pulling the mask strap out of position. A loose hood flushes cold water continuously, while an overly tight one is distracting and uncomfortable. Many hoods have a vent to release air trapped during descent, so check yours and burp out any trapped air before you go down.

New neoprene compresses and relaxes with use, so a boot, glove, or hood that feels firm out of the packaging usually settles slightly after a few dives. It should still be snug afterward rather than loose, because neoprene that stretches into a loose fit was probably oversized to begin with. Buy for a snug fit when new, but never for a fit that restricts circulation or breathing.

Yes, because every piece of neoprene you add is buoyancy, and a hood, boots, and thick gloves together can shift your weighting noticeably. Do a proper buoyancy check any time you change your exposure protection rather than assuming your usual weight still works. The weight-check procedure is covered in your training, and a dive professional can help you re-do it.

Rinse them inside and out in fresh water after every dive day, since they hold sweat and salt more than any other gear, and dry them fully inside-out before packing. Dry them out of direct sunlight and never on a heater, because heat hardens neoprene and weakens glued seams. Store them dry and unfolded, as damp neoprene sealed in a bag is how gear picks up a permanent smell.

The Echozip closes with a heavy-duty, non-corrosive #10 YKK toothed zipper running along the side of the boot. The zipper is non-corrosive and heavy duty, and elastic binding at the top of the boot resists wear.

The sole is 8mm thick and treaded. That thickness provides protection against punctures, stings and slips, so it suits rocky shore entries, wet boat decks and ladders. The patented ERGO shaped footbed and outsole are anatomically correct and match the profile of your foot.

This boot is offered in Black/Blue in whole sizes 04, 05, 06, 07, 08, 09, 10, 11, 12, 13 and 14. Check that your open-heel fin foot pocket can accept a 7mm boot before diving the pair. Call us at 888-701-4017 if you want help matching a size to your fins.

Yes. The Echozip is built in 3mm, 5mm and 7mm neoprene so you can match the boot to your conditions. The 7mm version listed here is aimed at cold water or long and repetitive dives.
