The 5mm dive boot by O’Neill is a great semi-dry cold water boot. Features 100% stretch neoprene, sealed seams and zipper to eliminate flushing, a poly fleece interior lining to wick moisture from the skin and retain heat, and a durable sole.
Sizing Tip: These boots run about 1 size small. Choose the next size up from your regular US shoe size. Example: Size 9 should order size 10.
Thickness Chart: Water temperatures are only guidelines. Many variables such as water temperature, depth, duration, and personal water temperature tolerance will impact your comfort level. It never hurts to order a thicker boot.
