  • Don’t let the “light” in the name fool you; this sock is no lightweight when it comes to comfort, durability and all the heavy-duty work you can throw at it. Our Light Tactical Boot is the perfect lightweight field sock. The 100% Merino Wool interior provides excellent moisture control and comfort while the Nylon exterior provides maximum durability and abrasion resistance.

    • Berry Compliant.
    • Cushioned Footbed with mesh top and leg.
    • Merino wool next to skin which feel great, is naturally anti-microbial, and flame resistant.
    • Nylon reinforcement on the outside of the sock for increased durability.
    • Heel Lock® provides heel security that limits the chances of a blister when combined with a properly fit boot.
    • Dynamic Toe Cup® limits the amount of material into box to prevent bunching in a critical area of the foot.
    • Knitting construction naturally moves the seam back from the sensitive toe area.
    • Excellent thermal insulation and moisture control.
    • Mid-calf height to work well with boots.

Got these for my son for Ranger School…both the light and heavy. He’s off the grid at the moment but tried them on prior to leaving and was really happy with them.

Amazing quality

I struggle with sweaty/stinky feet. I work 10 hour days and the socks have improved my quality of life and I'm grateful. I'll be a customer forever.

Best Socks on the Market

I've been a huge fan of FITS for a few years now and keep coming back. They are high quality and very comfy. I highly recommend these for work boots and for exercise!

First wear in 97 degree heat on a motorcycle

I first took these socks out of the packaging today, and I thought, "Damn, these things are really thick, my feet are gonna' roast in them! But when I put them on my feet, I noticed how breathable they are. Thick AND breathable socks??? It's sourcery I tell you! If my feet are uncomfortable, the rest of my body follows suit. I've been looking for long socks to wear with my motorcycle boots that were; 1) comfortable (no seam pressure), 2) didn't make my feet sweat, and 3) would last at least a year. Today I rode a half hour to my chiropractor and a half hour back home in 97 degree humidity. The "Fits - Light Tactical Socks" were definitely satisfying the first two requirements! I'll get back to you in 364 days for the third requirement. :O) A plug for the boots is in order because socks are only half the battle in feet comfort. Tactical Boots are freakin' awesome as well. I think I've found a heavenly pair of partners for my feet! I've had the boots for half a year and put 9,500 miles of riding through rain, snow, heat, and mud on them. Neither Fits nor Altaigear give me jack squat for a review. I just think reviews are a good place to get first hand knowledge of whether something works or not and I feel writing something besides "they're good" is helpful to prospective buyers. I give these socks a huge thumbs up. Ken J Kansas City, MO

Great Product

I have tried every tactical boot sock out there and after 10 years and 100s of miles rucked, I can honestly say this is the best product on the market. I have used them for every major ruck where what I did when I finished the movement mattered and they have never let me down. The sock securely fits to your foot so there is no friction between your foot and the sock, the sock takes all the friction between the sock and the boot.

Love these socks!

I have 6 different types of Fits socks. I threw away all of my other socks and replaced everyone with these! The light tactical are perfect for the warm season!

Light Tactical Boot

I can't rate these socks as they were purchased as a gift for my nephew who recently graduated from Marine boot camp at Parris Island,SC. However I personally have several other pairs of FITS socks and love them.


Sock Sizing

The Perfect Fit Starts With the Right Size.

Your sock size shouldn’t be a guessing game. Our socks range from small to double XL, but the best way to know the perfect fit for you is to match your shoe size to the chart on the left. That way, you’ll know the size you select will give you the fit and feel you expect.

Between sizes? Go with your gut, but rest assured that your socks will still fit great. If you receive your order and find yourself wishing you’d gone up or down a size, just let us know. We’ll happily send you replacements for your preferred size.

Concerned about laundry mix-ups? All FITS® socks are coordinated by color and size, based on the colors you see on the size chart. So, you won’t have to worry about mixing up your sizes with the other FITS® wearers in your home. (But stray socks mysteriously going missing in the dryer? Unfortunately, we can’t help with that.)

How Do You Determine Sock Size?

Sock sizes are typically measured in inches, not by your shoe size. So, a sock size 6-8 will comfortably fit someone whose feet are between six and eight inches long. However, at FITS®, we make it easy for you to choose the ideal sock size without having to measure your foot. Simply use our sock size conversion chart based on your shoe size to select the right fit for you. 

How Do You Measure Your Foot for Socks?

To measure your foot for socks, measure the length from the heel of your foot to the tip of your longest toe. The measurement in inches correlates to your sock size. For example, if your foot is 10 inches long, a sock size 9-11 should fit you comfortably. At FITS®, you can skip this step and find your sock size based on your shoe size using our conversion chart. 

What Is the Sock Size Conversion?

The sock size conversion refers to sock size compared to shoe size. While all companies may vary slightly on which size socks to purchase based on your shoe size, you can always measure your foot to find the right fit for you. 

What is Sock Size to Shoe Size?

Because sock sizes are determined by the length of your foot in inches vs. your shoe size, shoe and sock sizes differ. The FITS® sock size to shoe size conversion is as follows:

Knowing this makes it easy to choose the ideal sock size based on your shoe size without measuring your foot. 

What Age is Sock Size 9-12?

Sock sizes typically don’t correlate with age. For kids, age can be a general indicator of what size sock they’ll need, but everyone is different. An adult sock size 9-12 fits anyone whose feet are approximately nine to twelve inches long. For kids’ sock sizing, check with the company to find exact details to ensure your little one gets the perfect fit.
