FITS Socks Review

FITS Socks

Anyone who knows me knows that I am a huge sock nerd. I am not just talking about athletic socks here, I mean all socks.

So when I started to build out the gear and reviews section of the site I knew one of the mainstays would have to be sock reviews.

All too many athletes spend so much money on gear but simply settle for whatever socks are in their dresser. This is crazy especially being that a good sock can be the difference between a good workout or a bad one. Blisters or no blisters. They can even help prevent injuries!

FITS Socks Review

One of the companies that was gracious enough to let me test a couple of their socks was a company called FITS. Here is the excerpt from their site describing who they are:

FITS® is a premium sock brand resulting from the collaboration of third and fourth generation textile manufacturers to create the absolute best fitting sock in the marketplace as a response to an industry-wide epidemic of ill-fitting socks. Utilizing only the best raw materials available, FITS® incorporates innovative, proprietary engineering and technology to create the most comfortable, best-fitting sock in the world. The result: a product line that embodies the crucial connection between fit and performance.”

One of the biggest differentiators between FITS and other fitness sock companies is that they don’t purely produce athletic socks. They make socks for hiking, military, running, skiing and even just everyday lifestyle ones.


The first pair of socks that I tested out from FITS was their Ultra Light Runner (Minimalist) – No Show sock. There are numerous selling points for this sock but here are a couple of the main ones:

  • 66% Merino wool
  • Their patented Full Contact Fit® hugs the contours of your foot and stays put so there are no loose socks to rub you the wrong way. This no-show sock will not fall down into your shoe.
  • Fully vented top for breathability

The first thing I noticed when trying these socks on for the first time was how incredible they felt. They did an outstanding job with the Merino Wool proportions as you get all the comfort of a Merino Wool sock with the compression and lightness that comes from a synthetic athletic sock.

Another thing that stood out to me was just how well vented the top of the sock really is. A lot of companies claim that their socks are super vented but in reality you don’t notice any difference.

Immediately after putting these socks on I noticed how thin the material on top was and how well it allowed air to pass through. Not necessarily a game changer but certainly nice to have a product backing up its claims.

Full Contact Fit. FITS proprietary Full Contact Fit system was both a blessing and a curse in this sock. Basically the system is a proprietary stitching system built into each sock that is made up of 2 main features: Dynamic Toe Cup and the Heel Lock.

Let’s start with the Heel Lock. I love this. Every sock should have this feature. The best way to describe it is that the sock has a “deeper” heel allowing the sock to mold to your foot better. This results in a much more comfortable run and makes it so the sock never creeps down into the shoe.

Now onto the strangest feature on a sock that I have ever come across: the Dynamic Toe Cup. The idea behind it was straightforward enough. Make the toes of the socks actually mirror what peoples feet look like.

Nobody’s toes go straight across so why are all socks made this way? I get it. But putting a little pocket at the end of the sock for your bigger couple toes was not the way to accomplish this.

I will clarify that this may be one of the greatest features a sock company has every created for some people out there. However, with the way my foot is shaped and the way I wear socks, what happened was an extremely uncomfortable fit where my big toe was tight against the sock and then there was this little flap of extra material in front of my next 2 toes.

The minute I put my running shoes on I immediately knew this would be a bad run. I could already feel how strange this free-flying flap felt.

And I was right. From the first step all the way through 6 miles I was uncomfortable. The Dynamic Toe Cup was really messing with me. I hated it.

See that little pocket? Why?

The Bottom Line.

The bottom line with this sock is that it will either be the greatest sock you have ever owned or one with so much potential but just keeps annoying you. I think if they just kept the Heel Lock and eliminated the Dynamic Toe Cup they would widen their net and please a lot more people.

If they eliminate the Dynamic Toe Cup I’d easily rank this sock as one of my top 2 favorite running socks of all time.



The second pair of socks that I tried from the good folks at FITS was their Light Runner – Low. Their Light Runner line is what I would call their “everyday runner” sock. It’s a little heavier, a little more cushioning, not as tight, etc. Here are the Light Runner main features:

  • 73% Merino Wool
  • Full Contact Fit system
  • Cushioning only in the toe and heel areas

Unlike it’s Ultra Light cousin, the first thing I noticed when trying on the Light Runner was that it was a totally different sock.

It may share the namesake but it is different on almost all accounts. It is heavier, more Merino Wool, more cushion, and more.

The most pleasant surprise came when I put on the socks anticipating an annoying Dynamic Toe Lock but didn’t find any. I know they say that the sock features it but from what I could tell it didn’t seem to exist.

I would say the best part about this sock is once again the makeup of the sock. FITS really knocked it out of the park with the proportion of Merino Wool to synthetics in this sock as well.

I tried these out in a variety of situations and climates while running and can safely say that it held up in all of them. Merino Wool is tremendous in its ability to regulate temperature and this sock sure lived up to that.

In the heat this sock did a great job of keeping my feet from getting soaked. In the dead of winter in 15 degrees these socks made sure my toes never went numb.  

The cushion is also a great feature and is just enough for everyday use. It leans towards the more cushion side so if you really don’t like cushion then this may not be for everyday use.

The only negative I could find with this sock is that it tended to be a little “slippery”. Because the Merino Wool is so fine and the rest is synthetic I tended to have trouble hitting sharp turns in these if there was no moisture.

Once my feet would get a bit warmed up and damp the grip returned and they were great. But if you are running nice and easy in cold weather they may give you some trouble.

The Bottom Line.

The bottom line with these socks was that they are the perfect addition to any “everyday runner’s” wardrobe. Personally I only really love them for longer cold-weather runs but to each his own.

  1. Its like you read my mind! You appear to know a lot about this, like you wrote the book in it or something. I think that you can do with some pics to drive the message home a bit, but instead of that, this is wonderful blog. A great read. I’ll definitely be back.

  2. I’m amazed, I have to admit. Rarely do I encounter a blog that’s both equally educative and amusing, and let me tell you, you have hit
    the nail on the head. The issue is something that too few men and women are speaking intelligently about.
    I am very happy I found this in my search for something concerning this.
