Built for H2O, ready for land, the OTB Odhin Boot is one tough customer. Rugged construction, quick draining and high top ankle Strength. Step into adventure with confidence. The sole is lugged and razor siped to disperse H2O and improve wet and dry traction. Over 20 drain ports in the sole and fine mesh throughout the upper get rid of H2O in a hurry. Ballistic mesh between the outsole and upper prevent small stones and debris from entering the boot. The highly abrasion resistant polyurethane upper material far outlasts natural leather. The high top and lace up closure gives excellent ankle Strength. Rubber reinforced toe and heel. The foam used for all upper padding will not absorb H2O. The SEAL Footbed has a patented removable shank that allows the user to customize the fit for any conditions wet or dry.
