- Why Bulletproof Zone?
The Altama OTB Maritime Assault Low is a tactical boot built for water-based operations, designed to fit over dive fins used by militaries worldwide. Its non-water-absorbing construction, fast-draining ports, and quick-drying materials keep it functional before, during, and after water entry. Available in MultiCam and Coyote colorways across regular and wide widths, with sizes starting at 5.
Built for Water Operations
The OTB Maritime Assault Low is purpose-built for tactical water environments, not adapted from a standard boot. Front non-metallic drain ports allow water to exit freely as the boot flexes, so the boot sheds water during movement rather than holding it. The Ultron PU contoured insole is formulated not to absorb water, which means the boot's cushioning stays consistent whether the wearer is wet or dry.
Fin-Compatible Fit
The Maritime Assault Low is shaped to fit over dive fins used by militaries worldwide, a design consideration that affects the toe box geometry and overall profile. Operators who need to transition between swimming with fins and moving on land do not need to remove the boot to don fins, which matters when time and conditions are unpredictable.
Stability and Durability Under Load
A full-length, one-piece ABS shank runs the length of the boot, providing structural stability and support during ladder climbing, including caving ladders used in maritime assault scenarios. The quarter panels are constructed from high-abrasion 1000D Cordura, a heavy-duty nylon fabric that resists wear from rough surfaces and dries quickly after immersion. Air mesh linings move moisture away from the foot, and non-shine, rust-proof lace hardware resists corrosion from repeated saltwater exposure.

Who This Is For and Isn't
The Altama OTB Maritime Assault Low suits military, law enforcement, and tactical personnel who conduct water-based operations and need a boot that functions with dive fins, drains quickly, and transitions to land movement without a footwear change. The wide-width option accommodates buyers who need additional forefoot room, and the MultiCam colorway suits environments where pattern camouflage is required.
This boot is a purpose-specific maritime and water-entry design; its construction priorities (fin compatibility, drain ports, water-shedding materials) are not shared with general-purpose tactical or hiking boots. It carries no ballistic or stab-resistance rating and provides no protection against ballistic threats. Buyers seeking a standard land-operations boot or an insulated cold-weather boot should look at other options.
Common Questions
Will the OTB Maritime Assault Low fit over dive fins?
The Altama OTB Maritime Assault Low is specifically designed with a fin-friendly fit intended to accommodate dive fins used by militaries worldwide. The boot's toe box geometry and overall profile are shaped to allow fin wear without removing the boot, supporting fast water-to-land transitions during tactical operations.
How does the boot handle water drainage?
The OTB Maritime Assault Low features front non-metallic drain ports that allow water to exit the boot as it flexes during movement. The Ultron PU contoured insole is constructed not to absorb water, and the 1000D Cordura quarter panels are quick-drying, so the boot sheds water rather than retaining it after immersion.
Is the lace hardware rust-resistant for saltwater use?
Yes. The Altama OTB Maritime Assault Low uses non-shine, rust-proof lace hardware designed to resist corrosion from repeated exposure to water, including saltwater environments typical of maritime operations. The hardware is also non-reflective, which supports low-visibility tactical use.
What width options are available?
The Altama OTB Maritime Assault Low is available in both regular and wide widths. The wide option is offered in the MultiCam colorway. Buyers with a wider forefoot who need a secure fit while wearing the boot over fins should consider the wide-width variant.
Does this boot have any ballistic or protective rating?
No. The Altama OTB Maritime Assault Low is a tactical water-operations boot and carries no ballistic, stab-resistance, or armor rating of any kind. Its design priorities are mobility, water drainage, and fin compatibility. Buyers seeking protective footwear should review products with a stated protective rating.
Are there any shipping restrictions for this boot?
The Altama OTB Maritime Assault Low is footwear and is not body armor, so it is not subject to the body armor shipping restrictions that apply to states such as New York and Connecticut. No additional state-level shipping restrictions are indicated for this product.

The Bulletproof Zone Promise
When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.
1. Authorized dealer of every brand we carry
Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.
We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.
2. Best price, guaranteed
If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.
Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.
3. Free fitment consultation
Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.
4. Trusted by thousands of customers
Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.
