Swiftwick FLITE XT Zero Tab
They have great grip along the heel and toe box (more on that a little later!) super soft cushioning under my arches, added arch support up top, and a breathable upper the wicks sweat and moisture away from my feet.
These socks boast all of the hallmarks of a great pair of running shoes in a sleek and super comfortable pair of socks. They boost stability, provide modest compression to keep your feet feeling fresh, and look great.
Below, I wanted to really dive into how well these socks performed when I took them for a spin on a surprisingly warm September afternoon!
GripDry fibers for excellent grip inside of your shoes
Will not budge or slip down past your ankles as you run
Modest compression on your ankles for added stability
The ribbed band provides excellent arch support
Moisture-wicking materials keep your feet nice and dry
Invisible toe seam will not rub against your running shoes
Runs a little hot

When I took these running socks out of the package, I was quite surprised by the overall bulk of these socks. They have a nice and stretchy topside with a base that is a little dense and thick.
When I slipped them on my feet, that dense bottom side translated to an extra boost of cushioning and support. The topside is nice and stretchy, and contours really great to my feet and feels nice and supportive on the ankles.
The best part? The toe seam is completely flat and didn’t rub up against my running shoes when I hit the trails.
If you plan on sliding across your hardwood floors like Tom Cruise in Risky Business, you are in for a bit of a surprise. The toe box and the heel of this design are made from a thick and super grippy material that sticks to the floor, and the inside of your sneakers.
When out on the trails, it meant that these socks stayed firmly in place on my feet, and didn’t shift around even when engaging in quick agility work.
At first, I was a little worried that these fit a little too tightly along the topside of my ankle. They offer a contoured compression fit for better ankle support, and you can really feel the compression when you first pop these socks on your feet.
However, once I was finished with my warmup, that slight tightness in the ankle was completely gone. To really put the compression of the ankles to the test, I ran a few stairs sprints and loved that added stability these socks lent to my ankles.
The flat toe seam along the top of the foot was also a welcome feature. I am very sensitive to bulky toe seams, and they can really ruin my run.
The invisible toe seam on the FLITE XT did not rub up against the sides or top of my feet, which felt like I wasn’t wearing any socks at all! A good toe seam is super important to me, and these socks get an A+ in my book!
I also love that these socks did not budge an inch as I ran. Ankle socks have a reputation of migrating past your ankles and down into your shoes, but this wasn’t an issue with the FLITE XT. This sock stayed firmly in place on my ankles, which meant that I never needed to adjust them in the middle of my run.
The biggest test for any sock that offers modest compression is how your feet feel at the end of the run. I was a little concerned that the super tight fit or the ankle of these socks would cut a red ring of pain into the top of my foot. After a 2-mile run, I peeled off my socks and there wasn’t even an indentation on my ankle.
In fact, I wore these socks for the remainder of the day and peeled them off without so much of a trace that I wore socks that day.
What makes the FLITE XT unique is that it boasts GripDry Fibers. These proprietary fibers are what is responsible for that very unique grip on the heel and toe box. This blend utilizes Olefin materials for higher overall durability, grip, and comfort.
Even without running shoes, the ample padding on my feet felt incredibly plush. When I was finished with my run, I continued to wear these socks for the remainder of the day because they were just so cushioned and comfy!
These socks also host a blend of nylon, polyester, and spandex that stretches over your feet for a contoured fit that locks in place. The thicker materials on the underside of the foot ran a little hot for me, but the Fiber First moisture-wicking blend helped to keep them nice and dry.
My feet sweat at the mere thought of putting them inside of a pair of socks, so I was pleasantly surprised that even though my feet were hot- they were perfectly dry.
The comfort level of these socks was insane. The topside of the sock runs fairly par for the course. It is composed of super light and stretchy fabric that feels cool and breathable. It even has a ribbed band that runs on the topside of your arches for extra compression and support. The toe seam is top-notch, and the ankle band provides modest compression without feeling too tight or constricting.
What makes the FLITE XT stand out from the crowd is the construction of the bottom side of the sock. I really have never worn a pair of socks that deliver this amount of comfort. The Olefin-infused GripDry materials are grippy and tough but feel incredibly soft underfoot.
The black square of fabric that runs under my arches adds a lot of plush cushioning that I can really feel as I run. The performance of this sock almost feels like an orthotic insert that provides an extra layer of high-end cushioning and support!
With a high level of plush cushioning, the breathability of these socks suffers a bit. While the top side of my foot stayed impossibly cool, the underside of the foot got a little hot as I ran. It wasn’t a deal-breaker in the slightest, because I would gladly take a high level of cushioning in exchange for breathability.
While this sock ran a little hot, my feet were never soupy or sweaty. The blend of moisture-wicking materials in the base of this sock helps to move moisture away from your foot. When I popped off my running shoes, my feet were hot but perfectly dry.
Typically, when I am done with my run I take off my running shoes as well as my socks. However, these socks were so comfortable and kept my feet so dry that I continued to wear them throughout the course of my day.
The price of this sock is a little more expensive than your average pair of running socks, but for a very good reason!
These socks were built as if Swiftwick was constructing a pair of running shoes. Just like a pair of running shoes, the upper is built to be nice and breathable yet locking your foot in place and provides just enough compression to keep your stride nice and stable.
The outsole - I mean the underside - of the sock provides complex cushioning and excellent traction that locks in place to the midsole of your sneaker and the moisture-wicking properties keep your foot cool and dry. It may cost more than an average pair of socks, but the Swiftwick FLITE XT offers so much more than your average pair of socks!
I love ankle socks because they are lightweight and just look better with running shoes, but I gave up on them a few years back. I found that while they looked good, they always found a way to slip down over my heel and chill around my arches.
However, the Swiftwick FLITE XT ankle socks have renewed my love affair with ankle socks. I wore them for a quick 2-mile run around the neighborhood track, and later in the evening when I did a little circuit training with weights. No matter how much I moved, these socks stayed 100 percent locked in place.
The ample padding on the base of the sock felt incredibly nice but ran a little hot as I put a few miles behind me. While my feet felt hot, the moisture-wicking properties of the materials used helped to keep my feet impossibly dry. At the end of the day, I gladly welcome a little bit of heat for added stability and cushioning.
Plus, once I kicked off my running shoes my feet dried quickly, and I continued to wear them for the rest of the day.
