5.11 offers different boot lines meant to meet the needs of various people. Each collection of boots will fit into three categories depending on whether you need a roomy boot or a snug one. Here’s a simple guide to 5.11 boot sizing. 

  • Bio Fit – This is a low-profile design that’s great if you want the lightest-weight boots and high responsiveness. The collar of a Bio Fit boot is along your ankle. Examples of 5.11 shoe lines with this fit include the Pursuit series, XPRT 2.0, and Sky-Weight Family.
  • Tac Fit – With the collar just above your ankle, Tac Fit boots are a bit taller than the previous fit style. Examples are EVO Family, Tactile Family, and Ranger lines.
  • Pro-Fit – This one has the highest volume, providing the ankle support you need for high-profile tactical boots. The 5.11 shoes with this design are ATAC family, SPEED 2, and Company 2.0.

When it comes to b0ot length, you should use your standard US shoe size. Of course, since you’ll wear boots with boot socks, you should measure your foot length while wearing the socks.

There are numerous tactical boot brands offering military boots online. So how do you tell whether the boots are the best option for you? This section is a short buyer’s guide for boots to help you identify an excellent pair of boots.

1. Breathability

Wearing boots all day can cause your feet to sweat a lot. The accumulation of sweat inside your boots can encourage the growth of bacteria or fungi. These germs can cause foot infections that lead to the development of odors you want to avoid. 

Breathability refers to the ability of fabrics used in boot construction to allow air and water vapor to move in and out of the shoe. This creates a refreshing environment inside the boots that keeps your feet cool even when it’s hot. 

Boots usually feature a leather upper or nylon upper. Some are made using a combination of fabrics rather than a full-nylon or full-leather construction. These materials can be designed to cool your foot with moisture-wicking.

Moisture wicking refers to how fabrics can pull moisture away from your skin and out toward the surface. 

2. Lightweight Design

Another feature to look for in combat-type boots is a lightweight build. Even the best-looking tactical boots won’t give you much joy if you feel like you are wearing metallic footwear.

If you are walking long distances or climbing mountains and hills, you want your boots to be as light as possible. 5.11 offers light-duty boots that are durable but light enough for you to move without getting fatigued in minutes. 

3. Flexibility

When people think about boots in general, they picture something durable but stiff to walk in. This doesn’t have to be the case unless you are for cheap boots made from low-quality materials.

Nothing feels worse that not being able to walk properly because your boots are too stiff. 

Luckily, you can escape these issues with 5.11 boots. Even the full-leather tactical boots from 5.11 are still flexible enough to allow a superior range of motion. If you are looking for boots to wear outdoors, check out 5.11 comfortable hiking boots. 

4. Quiet Soles

In real-life combat scenarios, moving from one place to another silently can mean the difference between survival and annihilation.

Army boots should be designed to work without producing any type of noise as you walk in them.

If your boots squeak in enemy territory, you could reveal your position and put your life at risk. That’s why high-quality tactical boots should be silent on every type of surface. 

5. Tough Uppers

The last thing to look for in your boots is a long-lasting and reliable construction. The uppers of your boots need to be sturdy and durable to ensure they can withstand the harsh environments you wear them in. With a firm upper, you can rest assured that you’ll have ample ankle protection. 

The materials should also be designed to meet your specific needs. For instance, if you are a firefighter, you should choose boots with some degree of flame resistance.

You should also consider the type of weather you’ll be going into. Boots are great for helping people keep working through extreme weather conditions. Whether it’s dry weather or cold weather, your boots should be built to provide a suitable environment for your feet. 

Benefits of 5.11 Tactical Boots


You could be wondering what you’ll get when you buy a pair of boots from 5.11. So, here’s why 5.11 has the best boots for you. 

1. Waterproof

Wet or cold feet can be really uncomfortable, especially when you have to keep your boots on for hours. If you are outdoors in the rain or working in a wet environment, the only way to keep your feet dry is with waterproof boots. These boots are built to keep water out, ensuring your feet are nice and warm. 

2. Composite Safety Toe Protection

For those whose work involves lifting and carrying heavy objects, it’s important to have footwear that protects your toes. Bulky items can fall on your feet and crush your toes, leaving you immobile.

Fortunately, 5.11 boots come with composite toe caps, which keep your toes from being crushed without adding a lot of weight to the boots. Steel toe caps are heavy and make boots heavier, which can be a disadvantage if you want light footwear.

Additionally, composite toe caps are non-conductive, making them better for those who work with electricity. 

3. ASTM Certification

ASTM International determines the standards for safety shoes to help reduce workplace injuries. You’ll be glad to know that 5.11 boots are manufactured in compliance with the required standards making them a safe choice for professionals in different industries. 

4. Side Zips

High ankle boots can be hard to put on and take off because of the elaborate lacing system they feature.

Sometimes, you don’t have enough time to untie your laces to get your foot through. Luckily, 5.11 boots have a solution for you. 

Rather than taking a standard non-zip boot, you can go with 5.11 boots with side zips. These boots will give you an easier time wearing and removing them, saving you time and energy. 

5. Vibram Outsole

The outsoles of 5.11 boots are more durable than regular rubber soles because they are made from Vibram. This material is tough enough to withstand wear and tear on any terrain.

According to some customers, Vibram soles can last more than a decade without becoming thin. 

6. Slip Resistance

Another feature you want is a slip-resistant outsole. The outsoles on 5.11 boots are designed to provide traction and grip even on slippery surfaces.

Whether you are walking on ice, grease, or a wet floor, these soles will give you the stability you need to stay on your feet. 

Underneath, the lug (deeply indented patterns) on the soles also helps reduce the chances of slipping and falling. 

7. Polishable Toe

Boots aren’t just for the field; they are also important when appearing before your superiors or marching in a parade.

Your boot design has to have a formal appearance to ensure you don’t look casual as you report for duty. 5.11 boots can feature a polishable toe that ensures you look your best. 

8. Knife Pockets

If you engage in combat, you need every advantage you can get. That’s why some 5.11 tactical boots are designed with knife pockets where you can stash a blade.

This ensures you have an extra card up your sleeve even when you appear unarmed. 

9. Puncture Resistance

The soles of 5.11 footwear are built to be puncture resistant. This eliminates your anxiety when walking over sharp, piercing objects like glass or thorns.

So, these boots are great for exploring rough terrain in places like jungles. 

10. Comfort

While having functional boots is important, it’s just as critical to be comfortable in them. That’s why 5.11 boots feature an ortholite footbed to provide a cushion for comfort as you spend hours on your feet.
