inally, a pair of running socks that won’t wear out. They have a superpower: a blend of merino wool and Spectra fiber, whose durability, comfort, flexibility, and light weight are unmatched in the world of performance fibers. Fifteen times stronger than steel with a remarkably high abrasion resistance and tear strength, Spectra is used in bulletproof apparel for military and law enforcement. Still, the yarns are so light that they float on water and don’t absorb moisture, which means they’ll stay light and comfortable even when you sweat. Finally, Spectra is naturally cool to the touch and pulls heat away from the body during long runs. Add merino wool’s incredible natural properties, plus strategically placed compression and cushion zones, and you’ve got a pair of socks that’ll outperform all others.

We believe that socks are never a second-thought accessory. Most of us spend so much time choosing the proper footwear that supports and protects, but then many of us might toss on any old sock and head out for a run. Every aspect of your footwear should work for you, never against you. Sadly, many sock companies are created by those who don't understand the unique characteristics of running well enough to design a sock that works for athletes instead of against them.

Luckily for you, you've just discovered the one company created by two run-addicted brothers who went through the same disappointment in their socks and decided to do something about that, for good. They were tired of seams that made painful blisters, cheap material that wore away after a few uses, poor elasticity, and even worse support. These two brothers dedicated themselves in 2008 to create the best running socks for athletes. And they did!

And we're proud of our innovative designs and technology, but you don't have to take our word for it. On this page is a collection of our best running socks, voted for and chosen by customers all over the world. These are the running socks that have runners of all expertise levels raving.

With breathable, moisture-wicking materials like Flowtek™, Isolwool®, and Sorbtek, foot slippage due to uncomfortable sweat and moisture will practically be a thing of the past. Some of the features you'll find in our best running socks, depending on which design you choose:

  • Vented mesh for even better airflow to keep moisture low and allow evaporation more freely.
  • Crash padding in the forefoot gives more support and cushioning, helps prevention of blistering or further calluses forming for a smoother run.
  • Deep Heel and Arch Support specialized technology fights against sock slippage, keeping them in place
  • Option zone compression construction to ensure a more natural, comfortable fit.
  • Anti-bacterial properties with Merino wool and polypropylene socks along with superior moisture-wicking capabilities
  • Hot or cold wear
  • And a shocking, industry-breaking lifetime guarantee.

Each of our best running socks has been gathered based on customer reviews and purchases, ensuring that you don't have to just take our word for it!
