Overview & Origins of the Altama Maritime Assault

The Altama Maritime Assault boots trace their origins back to the demanding requirements of U.S. Navy SEALs and other special forces units conducting amphibious operations. For nearly five decades, Altama has been crafting military-grade footwear that meets the rigorous standards of America's elite fighting forces. What sets the Maritime Assault series apart is its unique design philosophy: create a boot that performs equally well in water and on land.
I first encountered these boots during a conversation with a former Navy diver who swore by their versatility. He described them as "Chuck Taylors that can actually handle serious work," and after extensive testing in various environments, I understand exactly what he meant. The altama maritime assault represents a fascinating convergence of military necessity and civilian practicality.
The mid-cut version strikes an ideal balance between ankle support and mobility. Unlike traditional combat boots that prioritize durability over comfort, or civilian shoes that sacrifice performance for style, these boots occupy a unique middle ground. They're equally at home on a mountain trail, in urban environments, or during water-based activities. The design team at Altama clearly understood that modern operators need gear that adapts to rapidly changing mission parameters.
What makes the Maritime Assault particularly interesting is its crossover appeal. While originally designed for military use, these boots have found favor among outdoor enthusiasts, urban explorers, and anyone seeking reliable, versatile footwear. The tactical heritage is evident in every design element, from the reinforced toe cap to the strategic placement of drainage ports. Yet the overall aesthetic remains understated enough for civilian wear.
The Maritime Assault boots are available in multiple configurations, including low-cut and 8-inch versions, but the mid-cut version offers the best balance of protection and mobility for most users.
Key Features & Technology
The technical specifications of the Altama Maritime Assault boots reveal a sophisticated approach to amphibious footwear design. Every component serves a specific purpose, contributing to the overall performance in challenging environments. Let me break down the key technologies and materials that make these boots unique.
Construction and Materials
The upper construction utilizes high-abrasion 1000D Cordura fabric panels, a material originally developed for military applications. This synthetic fabric offers exceptional tear resistance while maintaining breathability—a critical balance for footwear that might encounter sharp rocks, coral, or other hazards. The quarter panels feature this durable material in areas most prone to abrasion during climbing or scrambling activities.
The toe reinforcement deserves special attention. Rather than using traditional leather or basic rubber, Altama employs a specialized rubber compound that provides protection without compromising the boot's ability to fit inside diving fins. This fin-compatible design was a specific requirement from maritime operators who needed footwear that could transition seamlessly from boat to water to land operations.
Drainage System
Front non-metallic drain ports allow rapid water evacuation during movement, preventing the boot from becoming waterlogged.
Support Structure
Full-length ABS shank provides stability for ladder climbing while maintaining flexibility for natural foot movement.
SEAL Rubber Outsole Technology
The outsole represents perhaps the most critical component for amphibious operations. Altama's SEAL Rubber compound was developed specifically for wet traction, offering superior grip on wet rocks, boat decks, and other slippery surfaces. The tread pattern features strategically placed lugs that channel water away from contact surfaces while providing multiple grip points.
During my testing on various surfaces, including wet granite, wooden docks, and metal grating, the traction performance consistently impressed me. However, it's worth noting that this specialized rubber compound tends to be somewhat noisy on hard surfaces—a trade-off between grip performance and stealth that users should consider based on their intended applications.
Weight Specification: At approximately 13.5 oz (385g) per boot, the Maritime Assault strikes an excellent balance between durability and weight savings. This is significantly lighter than traditional combat boots while maintaining structural integrity.
The air mesh lining system deserves recognition for its moisture management capabilities. Rather than using traditional fabric linings, Altama incorporates a mesh system that promotes airflow while wicking moisture away from the foot. This becomes particularly important during extended wear in humid conditions or when transitioning between wet and dry environments.
For tactical applications, the rust-proof lace hardware ensures reliability in saltwater environments. The low-profile laces are specifically designed to minimize pressure points when wearing diving fins—a detail that demonstrates the thoroughness of the design process. Similar attention to detail can be found in quality Tecovas boots and other premium outdoor footwear.
Sizing & Fit Guide
Getting the right fit with Altama Maritime Assault boots requires understanding their unique sizing characteristics. These aren't your typical athletic shoes or casual boots—they're designed with specific functional requirements that affect how they should fit your feet. Based on extensive research and user feedback, I've compiled this comprehensive sizing guide.
Official Sizing Recommendations
Altama's official guidance suggests sizing up one full size from your normal shoe size, and 1.5 sizes if you typically wear a half-size. This recommendation stems from the boot's intended use—they're designed to be worn with minimal socks or even barefoot for diving applications. However, real-world experience suggests this guideline needs refinement based on individual foot characteristics and intended use.
Critical Fit Consideration: The narrow, fin-compatible design means these boots fit differently than standard footwear. Users with wide feet should pay particular attention to width accommodation.
During my fitting process, I tested multiple sizes to find the optimal balance. Starting with my normal size 10, the boots felt uncomfortably tight across the forefoot. Moving to 10.5 provided adequate length but still felt restrictive. The size 11 proved to be the sweet spot, offering enough room for normal socks while maintaining security during active use.
Fit Characteristics by Use Case
Diving/Water Use
Follow Altama's +1 to +1.5 size recommendation. Boots should accommodate fin wear with minimal sock thickness.
Hiking/Outdoor
Size up 0.5 to 1 full size to accommodate hiking socks and potential foot swelling during long activities.
Urban/Casual
Size up 0.5 size for comfortable daily wear with normal socks. Some users prefer their normal size for a snugger fit.
The break-in period varies significantly among users. Some report comfortable wear immediately, while others experience pressure points that resolve after several days of use. The structured construction means these boots maintain their shape well but may initially feel stiff compared to athletic footwear. This characteristic is shared with other quality tactical boots like Brunt boots and similar military-inspired footwear.
My Experience with the Altama Maritime Assault
After six months of intensive testing across diverse environments, I can provide a comprehensive assessment of the Altama Maritime Assault boots' real-world performance. My evaluation included urban hiking, coastal exploration, stream crossing, and various weather conditions throughout the Pacific Northwest.

Initial Impressions and Break-In Period
My first encounter with these boots occurred during a ranger-led program at Olympic National Park. The ranger mentioned seeing increasing numbers of visitors wearing military-style boots, and specifically praised the Maritime Assault series for their versatility on mixed terrain. This recommendation prompted my purchase and subsequent testing regimen.
The initial break-in period lasted approximately two weeks of regular wear. Unlike traditional leather boots that gradually conform to foot shape, these boots maintain their structural integrity while becoming more comfortable through compression of internal padding and slight material relaxation. The first few days revealed pressure points around the forefoot, particularly during extended walking sessions.
I found that alternating between the standard insole and aftermarket options significantly improved comfort during the break-in phase. The original Ultron PU insole serves its intended purpose for amphibious use but lacks the cushioning many users expect for extended terrestrial activities. Swapping to quality hiking insoles transformed the comfort profile, though this modification does reduce the boot's quick-drying capabilities.
Performance in Various Environments
The drainage system proved highly effective during stream crossings and coastal exploration. Water evacuation occurs rapidly during movement, typically clearing completely within 10-15 steps after exiting water. However, this same feature becomes a liability during rain exposure—water entry is as efficient as water exit. For wet weather hiking, waterproof gaiters or alternative footwear may be preferable.
Urban performance exceeded expectations, particularly on varied surfaces. The SEAL rubber compound provides excellent traction on wet concrete, steel grating, and smooth stone surfaces common in urban environments. However, the trade-off is increased noise generation compared to standard sneakers. This characteristic becomes most apparent on hard indoor surfaces where the sound signature is quite distinctive.
For extended hiking applications, comfort limitations become apparent after 8-10 miles on hard surfaces. The stiff sole construction, while excellent for ladder climbing and technical applications, transmits significant impact to the foot during prolonged pavement walking. This characteristic mirrors feedback I've observed with other tactical footwear brands like Thursday Boots, where military heritage influences design priorities.
Seasonal Performance: These boots excel in spring and fall conditions when temperatures are moderate and occasional water contact is likely. Summer use requires careful sock selection to manage moisture, while winter applications may need additional insulation.
The most impressive performance came during a multi-day backpacking trip that included river fording, rocky scrambling, and camp-to-trail transitions. The boots' ability to transition between wet and dry conditions without extended drying time proved invaluable. While not as comfortable as dedicated hiking boots for pure trail work, their versatility eliminated the need for multiple footwear options.
