O'Neill's 3 mm Ninja boot has a split-toe design and a close anatomical fit for board and water sports. The listed construction includes FluidFlex on the inside, a durable Krypto forefoot, an anti-flush strap at the shin, and glued, blind-stitched seams.
Check the split-toe shape against your personal comfort and the fin or footwear you plan to use. This model's surf-oriented design should be evaluated carefully before pairing it with scuba fins or using it for rocky shore entries.
