The popular Delta 5mm dive boot features a rugged yet flexible outsole and rubberized armor, yet still feels very light on the foot. A revised ankle diameter and contoured top improve fit and make sliding the YKK zipper up and down even easier. The full-cut design ensures a comfortable, cramp-free fit, even for wide feet. Reinforcement on the top of the foot pads the fin pocket edge. The boot's non-slip tread leaves no marks, a feature boat owners always appreciate. They offer great comfort, and you'll be glad to wear your Deltas on your next cold water dive or when crossing rocky shorelines.
