Altama OTB Maritime Assault Boot - Low Height

Are the Altama OTB Maritime Assault Low boots compatible with dive fins?

Yes. The Altama OTB Maritime Assault Boot – Low Height features a fin-friendly profile specifically designed to fit most military dive fins used worldwide. The streamlined toe box and absence of a raised heel accommodate standard open-heel and closed-heel fins without requiring fin straps to over-extend. The oversized pull loops are sized for dive gloves, allowing the boot to be donned and adjusted while wearing full hand protection in or near water.

How do the drain ports work on the Altama OTB Low boots?

The OTB Low features front non-metallic drain ports positioned at the lateral flex point of the forefoot. Each time the wearer takes a step and flexes the boot, the ports actively pump water out of the interior. This active drainage mechanism allows the boot to shed water during movement rather than requiring passive drainage time while standing still — a critical operational advantage in OTB scenarios where operators need to transition immediately from water to land movement.

What is the SEAL rubber outsole and why is it used on the OTB boot?

SEAL rubber is a high-traction compound originally developed for rock climbing footwear. It provides exceptional grip on wet surfaces including ship decks, wet aluminum ladder rungs, slick rock shorelines, and wet concrete — conditions where standard tactical boot rubber compounds perform poorly. The OTB's outsole incorporates a wavy, zigzag-cut tread pattern in the SEAL rubber that maximizes wet-surface bite without the aggressive lugs of land-focused boots that can snag on ship deck seams and ladders.

Do the Altama OTB Low boots run true to size?

The Altama OTB Maritime Assault boots fit slightly narrower than average due to the fin-friendly profile. Altama recommends going up one half-size if you wear a half size, as the boots are only available in whole sizes. Wide-foot wearers should go up a full size. The boots are listed in Men's US sizes and are available in Regular width (D) in sizes 9–13. A wide (EEE) variant is available in some colorways — check the product variant selection for W sizing.

Are the Altama OTB Low boots appropriate for non-maritime tactical use?

Yes. The OTB Low's durable 1000D Cordura® construction, SEAL rubber traction, and ABS shank make them effective for general tactical use beyond maritime operations — including patrol, training, and urban operations. The low-profile shoe height provides unrestricted ankle mobility preferred by some operators for dynamic movement. For ankle support in rugged terrain or extended ruck movements, the Altama OTB Mid Height version provides additional lateral ankle protection while retaining the same amphibious design features.
