The Aqualung Ultrazip is a 5mm neoprene scuba boot engineered for comfort, protection, and ease of use. It combines an anatomically correct ERGO-shaped footbed with durable construction and features designed specifically for fin use.

• Ergonomic: Patented ERGO-shaped footbed and outsole match the profile of your foot to reduce water retention and provide comfortable support.
• Protective: Thick treaded sole with a puncture-resistant felt inner layer, plus reinforced toe and heel caps for added safety.
• Slip-resistant: Deep grip tread pattern helps keep you steady on wet surfaces.
• Comfortable construction: Minimal seams are placed away from the widest parts of the feet to reduce chafing; ribbed pattern embossed in the 5mm neoprene contours with every movement.
• Durable closure: Heavy-duty, non-corrosive #10 YKK toothed locking zipper.
• Designed for scuba: Low-profile heel, toe, and top-of-foot patches provide support and abrasion resistance in fin pockets and straps.
• Easy on: Articulated cuff provides a secure grip when pulling the boot on.
• Eco-conscious packaging: Ships with minimal carbon footprint packaging and no plastic bags.
