This is the Aqua Lung 7mm Superzip Boots Scuba Diving Booties Tread Sole

Features:

• Ergonomic: Like the rest of the Aqua Lung boot line, the Superzip uses our patented, anatomically correct ERGO™ shaped footbed and outsole to match the profile of your foot, preventing excess water retention and offering comfortable support
• Protective: 8mm-thick treaded sole provides premium protection against punctures, stings, and slips. For added protection and durability, the panels on the heel cap, toe, and top of the foot are twice as thick as in the standard boots!
• Warm: 3, 5 or 7mm neoprene upper for the right amount of warmth in any conditions
• Comfortable: The Superzip boot uses just a few seams, which are placed away from the widest parts of the feet to minimize chafing
• Eco-Conscious Packaging: Ships with minimal carbon footprint packaging. No plastic bags.
• Durable closures with a heavy-duty, non-corrosive #10 YKK toothed zipper. Elastic binding at the top resists wear and tear

We get it, finding a comfortable and long-lasting 7mm boot can be tough. Our 7mm Superzip Boots finally give divers the ergonomic boot they've been waiting for. The durable YKK zipper has been sewn onto our strongest Supratex neoprene to prevent it from tearing out. Durable and comfortable, Superzip Boots can stand up to whatever your adventures throw at them.
