Best Athletic Sock for CrossFit

Let’s review the best athletic sock for CrossFit.

A sock review? Yes, a sock review. Let me explain.

Darn Tough Vertex Micro Crew Ultra-Light Cushion - Running Sock
Darn Tough has made in the USA socks like the Darn Tough Vertex Micro Crew Ultra-Light Cushion – Running Sock. It’s great for CrossFit too – the cushion helps with those minimally padded cross trainers like the Nike Metcon 5 and Reebok Nano X.

I’m the guy that always bought cheap socks.

You know, whatever was in the bargain bin at the front of the store – the 12 pack of paper-thin cotton socks for $20.

But after I started buying (and testing) real athletic socks – I can’t bear to wear the cheap ones any longer.

So ditch those Walmart socks (the ones that get a hole the 2nd time you wear them) and check out some of these better options for your workout:

1/4 Sock Lightweight with Cushion (Darn Tough) Here's an athletic sock from Darn Tough. This sock is light up top for breathability but has extra cushion on the bottom. Made with 43% Merino wool - one of nature's greatest materials. Made in the USA, guaranteed for life.

Element No Show Tab Light Cushion (Darn Tough) Want a no-show height athletic sock? Check this one out - 44% Merino Wool and 5% Lycra Spandex for a perfect fit. And it's got a breathable mesh top with nice cushion on the bottom. Like all Darn Tough's socks these are guaranteed for life.

Vertex Micro Crew Ultra-Light Cushion (Darn Tough) Here's a running sock from Darn Tough in crew height - if you want more coverage. These are much like the other Darn Tough socks - and this is the version with CUSHION - because we think that's what works best for CrossFit. Merino wool/Nylon/Lycra Spandex - made in the USA

All-Day Performance Dress Sock (ALMI) Road warrior by day and fitness junkie by night? Save a lot of room in the roller bag by getting these dual-purpose performance socks. They work with a dress shoes and dress pants - or with your cross trainers in the gym.

No-Show Running Sock (MudGear) MudGear makes socks for mud runs and obstacle course races (OCR). But, this gear works great for the CrossFit WOD too, because it's tough, comfortable, and high-performance. This no-show running sock is made in the USA and fits like a dream. Because it's from MudGear it is also max wicking and fast draining!

Let’s take a closer look.

Athletic Sock Versus Running Sock – What’s the Difference?

First of all, what is an athletic sock anyways?

Is an athletic sock and a running sock the same thing?

Sort of. Here’s the key differences.

Athletic socks are for general fitness activity and exercise.

They tend to be light-weight, breathable, and usually have at least a mild compression effect to them – thanks to a comfortable, stretchy fit.

(The theory with compression socks is that they offer the same performance and recovery boost that other compression gear does).

So how is a running sock different?

Running involves a lot of repetition, impact, and moisture.

So, running socks tend to have more cushion (on the bottom) than your average athletic sock.

They also are normally some form of moisture wicking material – to get that sweat away from your skin.

Lastly, running socks will normally help combat the mortal foe of any runner – blisters.

And while running socks are a great idea if you are running a lot – they might be overkill if you are doing a more balanced functional fitness style workout – like CrossFit.

(But on the flipside – wouldn’t you like a more cushioned sock to go with those no-cushion cross training shoes you are wearing? I know I would.)

Having said all that, there’s a LOT of overlap between athletic socks and running socks.

Therefore, we’re going to look at a number of options – and let you decide what works best for your workout.

Best Sock for CrossFit?

So what do we want in an athletic sock for CrossFit?

Here’s my “Wish list”.

I like a slight compression effect – something that gives a tight, but comfortable fit.

Why? Well the compression effect can help reduce muscle fatigue – and boost your recovery ability.

There’s also a thought that they help reduce the incidence of muscle strains.

All that – and it feels nice – so let’s make sure there’s some compression effect in our socks.

How about cushion?

For CrossFit (and any functional fitness style workout) we’re probably not running much – maybe a few hundred meters. (Or maybe not at all – if you are lucky).

But, do you wear cross trainers like the Reebok Nano X, Nike Metcon 5, or something similar?

Those shoes have close to ZERO cushion. It’s the nature of the beast – they are cross training shoes – they have little cushion so they feel stable under a heavy squat, deadlift, clean, or snatch.

All-Day Performance Dress Sock
I love my Reebok Nano X cross trainers – but standing or walking in them all day long is not nice. The extra padding in the heel and toe of the ALMI All-Day Performance Dress Sock makes a noticeable difference.

And while that’s great while we are lifting heavy weights, those shoes tend to be less comfortable at all other times.

If we can’t change the cushion in our shoe, we certainly can put more cushion in our sock – and that is one area where running socks excel.

Some people like to wear tall socks for deadlifting – it helps keep the bar from scraping up your shins as you lift.

(If you are doing the deadlift right the bar is CLOSE to your body at all times).

If you want that, look for a sock in the “over the calf” length. We’ll consider that an optional requirement here though.

Lastly, CrossFit WODs tend to be a hot and sweaty affair.

If we can get any sort of moisture-wicking (to get the sweat away from our skin), anti-microbial properties, and thermo-regulation or breathability – that’s a good thing.

Let’s look at the contenders – we’ll tell you were each of these rank in our hands-on (feet on?) testing.

Athletic Socks from Darn Tough

Let’s look at athletic and running socks from Darn Tough.

These are all made in the USA (knitted in Vermont) and they all use some amount of Merino wool (which may be imported).

Why Merino wool? It’s one of nature’s wonder materials. Keeps you cool when it’s hot, and warm when it’s cold – that’s what we call “thermoregulation”.

It’s 6 times more durable than cotton, and is naturally anti-odor and anti-microbial.

This isn’t old fashioned wool – Merino wool is much finer than traditional wool.

Here’s the 1/4 Sock Lightweight with Cushion. Being 1/4 Sock Height means it sits just above your ankle. This feels perfect – fast and light – and it will work with any running shoe or cross trainer.

Darn Tough Athletic 1/4 Sock LIghtweight with Cushion Sock
The 1/4 Sock Lightweight with Cushion from Darn Tough is a great sock for what we’re looking for. Light and breathable, but with cushion on the bottom. Made with Merino wool

This specific version of the sock has extra cushion on the bottom.

That means it makes those bare-bones cross training shoes a lot more comfortable.

Darn Tough Athletic 1/4 Sock LIghtweight with Cushion Sock with Nano X
Shown with the Reebok Nano X cross trainers, the height is perfect – and the extra cushion helps make these minimally cushioned cross trainers more comfortable for long periods.

These are made from a 53% Nylon/43% Merino Wool/4% Lycra® Spandex bland.

That means a stretchy, comfortable fit – no bunching or excess material.

Want a shorter height? We’d recommend you look at the Element No Show Tab Light Cushion.

Darn Tough Athletic No Show Tab Lightweight Sock
Cushioned bottom, lightweight breathable mesh top, and Merino wool/spandex in a no-show height.

It’s basically got all the same features as the other sock – but in a no-show height.

Being a shorter sock, it does have a higher Lycra Spandex count – to make sure the fit is perfect.

The “tab” on the heel also helps ensure these short socks stay put.

Darn Tough Athletic No Show Tab Lightweight Sock
The tab on the heel helps make these more comfortable – and ensures they stay put.

And if you are looking for something even lighter – they make a version of that sock without the bottom cushion.

Darn Tough Athletic No Show Tab Lightweight Sock with Nano X
There’s not much to see of a no-show sock – but here they are with the Reebok Nano X.

How about a running sock option from Darn Tough?

The Vertex Micro Crew Ultra-Light Cushion is our top pick.

Darn Tough Vertex Micro Crew Ultra-Light Cushion - Running Sock
Micro Crew height comes up to your ankle – and this is a ultra-lightweight running sock. Why add weight to your feet? These do have cushion on the bottom for extra comfort.

How does this “running” sock differ from your average athletic sock?

It’s ultra-lightweight and made with 51% Merino wool/43% Nylon/6% LYCRA Spandex. Why add weight to your run?

At the same time, this is a cushioned option (again – for reasons we already explained).

Darn Tough Vertex Micro Crew Ultra-Light Cushion - Running Sock with Nano X Cross Trainer
These cushioned socks work great with cross trainers – like these Reebok Nano X CrossFit shoes.

All that and it looks nice.

By the way, all these Darn Tough socks are “guaranteed for life”.

No strings. No conditions. For life.

Are these expensive socks? Not if they last forever – and if you love wearing them (and you will).

Here’s a close-up of the upper of the sock – they are very high-quality.

Darn Tough Vertex Micro Crew Ultra-Light Cushion - Running Sock Closeup
High-quality, with a stretchy, comfortable fit for all day comfort.

These are great socks.

The Wonders of Merino Wool
Merino wool makes for a much better performance fabric than regular wool – here’s why:

  • Moisture Wicking
    As your body heats, Merino Wool absorbs moisture before it turns into sweat on your skin, and releases it, leaving you dry.
  • Thermo Regulating
    There is a natural crimp in wool fiber that provides pockets of insulation—holding and releasing heat dependent on what the body is doing.
  • Anti-microbial
    Odor resistance is unique to wool. The chemical structure stops sweat and bacteria build-up. So go ahead and take a whiff.

Athletic Socks from ALMI

Any road warriors in the audience?

For me personally, I travel a lot for work – and always have. But I never check a suitcase – it’s roller bag or bust for me.

So that means I’ve got to be choosy about what I pack – and the professional settings I’m in usually equates to dress pants and dress shoes (and occasionally a tie – Ugh!).

ALMI (“A Little More Invincible”) makes the All-Day Performance Sock.

All-Day Performance Dress Sock
The All-Day Performance Dress Sock is made to work in the office, or in the gym. Why pack two pairs of socks when you can do it all with one pair?

What’s special about these?

All-Day Performance Dress Sock
The upper part of the sock has a breathable mesh zone, and the heel and toe are padded nicely.

They are the perfect blend of dress and athletic – for the office during the day – and the gym in the evening.

These are 200 needle fine knit – just like your other big-boy dress socks. Those ones you paid a lot of money for. (Can you wear those in the gym?)

All-Day Performance Dress Sock
Here’s the heel. You can see the breathable mesh zone (starts in the center of the picture and wraps around the top).

They have a conservative look – but still pack the performance features we look for in a premium athletic sock. They are available in 3 colors.

They have the light compression and comfortable, stretchy fit that I prefer.

They have a lightly padded heel and toe. That makes them great for standing all day in dress shoes – and they work nice with the Reebok Nano X and Metcon 5 shoes.

The padded heel works great in shoes where the heel is just a tiny bit loose – this sock can make the difference between too loose – and a perfect fit. (For this reason I love to wear these with both my Legacy Lifter and Romaleos weightlifting shoes).

They also provide excellent arch support.

All-Day Performance Dress Sock
Here they are with the Reebok Nano X – which makes for a nice combo (the extra padding in the sock improves the cushioning situation in the Nano X).

See those stripes? That’s not just a fancy design. Those are breathable mesh zones.

These are also anti-microbial, anti-odor and built for comfort and durability.

ALMI gives you a generous 30 days to try – and return them if they aren’t awesome.

I’ll bet you keep them though.

Here’s one last thing we like about these – the more you buy, the cheaper the price. That’s nice.

Athletic Socks from MudGear

MudGear makes tough stuff too – they have to.

Here’s the MudGear No-Show Running Sock (Buy on Amazon) – It’s a great no-show sock that meets all our criteria for an excellent workout sock.

MudGear No-Show Running Socks - Black-Gray

They specialize in apparel for mud runs and obstacle course races (or OCR, as it is known).

MudGear No-Show Running Socks - Black-Gray
Here is the MudGear No-Show Running Socks with the Nike Air Zoom Pegasus 37 running shoe. There’s not much to see, because they are no-show height.

What should you expect? Comfort and toughness – and an improved ability to handle water immersion.

(Remember, they build stuff for mud runs).

MudGear No-Show Running Socks - Black-Gray
You can see the “MudGear” branding in most shoes.

These are made in the USA – and they have an extra supportive midsole – and that means no slipping and bunching.

(You can’t stop to adjust your socks when you are running a race against the clock).

They have a good level of cushioning on the sole.

MudGear No-Show Running Socks - Black-Gray
You can see the top part of the sock is fairly breathable.

These have been put to the test by experienced trail runners and endurance runners too.

Based on my testing – these are great socks for CrossFit – and just about anything else.

Why Cheap Socks Stink

If you are buying in bulk, you can’t beat the price of that dozen-pack of thin cotton socks.

But here’s where those are a false economy.

They get holes – QUICKLY. I’ve had Walmart socks that went south literally the first time I wore them. They were just TOO thin (that’s why they are so cheap).

They never have any compression effect and the fit is usually very poor. With no stretch to them, they fit your feet like a trash bag. Lots of bunched up material in the toes, in the heel, or both.

The elastic tends to be poor – or outright fail. They certainly don’t get better with age.

Lastly, cotton is nice for some things – but it is NOT considered to be a high-performance material.

The socks we’ve reviewed here are made from high tech, premium materials – and provide high performance.

Best Athletic Sock for CrossFit – In Summary

Cheap socks for your CrossFit workout are a false economy.

They fit poor, they don’t help your performance, and they don’t last long.

The best athletic sock for CrossFit will give you a performance boosting compression effect, breathability, sweat wicking, and a nice, comfortable fit.

Perhaps more importantly – they’ll work consistently – over and over and over.

I don’t mind paying a lot for socks – especially if they last a long time.
