O'Neill's Hyperfreak range is renowned as boasting arguably the most flexible neoprene on the market, and that's what the focus of design has been in the Ninja Booties. These booties are designed with TB3-X neoprene, a seriously flexible and supple neoprene that uses an Envy Foam core rubber (basically a neoprene with a whole lot of volume and not much cell wall for max stretch) as well as TB3-X jersey lining. Basically their most flexible neoprene yet - so you can be sure you'll be feeling unrestricted in the surf. Of course, some durable Krypto Forefoot material is employed on the base of the boots to prevent rapid wear and tear of this super-supple neoprene and to give you some added grip. O'Neill Hyperfreak Ninja Split Toe Boot 3mm Features: TB3-X Neoprene: A super-flexible neoprene that uses a low-density foam core to maximise stretch with TB3-X interior and exterior jersey lining. Their most flexible neoprene to date. Durable Krypto Forefoot: Protects the neoprene from wear and tear and gives you something grippy and firm to stand on. Anatomical Fit: Not just panels whacked together - they've been shaped to match the contour of the average foot for a better feeling fit. Anti-Flushing Ankle Strap: Stops water from flushing in at the opening of the booties, keeping your feet warm. Split-Toe Design: You've got to be able to feel your board beneath your feet, and finely adjust your balance, which a split-toe design allows you to do.
