The popular Delta 5mm dive boot, updated for 2019, maintains its sturdy but flexible outsole and rubberized protective armor, yet still feels very light on the foot. A revised ankle diameter and new contoured top improve fit and make sliding the YKK zipper up and down even easier. The full cut design creates a comfortable, cramp-free fit, even for wide-shaped feet. The reinforcement on the top of the foot provides both cushion and protection against the edge of the fin pocket. The boot's anti-slip tread is non-marking, a feature boat owners always appreciate. Offering lots of protection and comfort, the next time you're diving cold water or traversing rocky shorelines, you'll be glad to be wearing your Deltas.
