Product Description

Made Tougher, Like You.

In a world where socks were too soft...

In 2012, we fell deeply in love with Obstacle Course Racing.  It ripped us off the treadmill, out of our comfort zone, and unleashed us into the wild outdoors.  Events like Spartan Race, Tough Mudder, BattleFrog, and Savage Race tested us and our gear to the limits.  We learned that gym socks got soggy in the mud, and that most running socks were made for roads.

We set out to make a tougher trail running sock.  

MudGear was born to do what nobody else could do; make a performance sock resilient enough to withstand outdoor race conditions and tough enough to help protect racers from the course itself.

They Said It Couldn't Be Done - They Forgot About American Muscle

The American sock industry has a long history of quality engineering, but cheap labor gave rise to importing.  While others cut costs and cut corners, we knew the world's toughest and best socks should be designed and made in the USA.  Leveraging decades of experience with top brands, our designers are experts in the technology of performance sock construction.

Using Premium Yarns and Strong Construction

The difference comes from starting with American yarn blends that are chosen for their durability and comfort.  Next, we engineered our socks to achieve specific performance results for their ventilation, moisture management, and abrasion resistance.  We built in a medium level ankle compression to keep out dirt from the trail.  In layman's terms, our trail socks make your feet feel great.

And Tested In The Worst Conditions Possible 

Normal testing of running socks involves a simple abrasion test to see how quickly they show wear.  Our testing involves putting them on the world's top obstacle racers and trail runners for trips up and down mountains all day in all types of weather.  We test for wicking by fully submerging them in muddy water, and we test durability by ultra distance marathons.  

Through It All, We Were Made Tougher

Nobody said it was going to be easy.  We heard a lot of "it's not done that way" and "it's not practical".  But all the trials and trails made us tougher, and we're now proud to offer the toughest (and most comfortable) trail running sock on the planet. It also happens to be our go-to sock for training, Spartan Stadium Races, and everyday wear.

Why Choose MudGear

High Ankle Shield Keeps out dirt and rocks

The first thing you'll notice about these socks is the relatively high ankle that is tight enough to keep out dirt and rocks, but it's not a tight compression fit.  The footbed is soft and cushioned but not thick in a way that will soak up and hold water or mud.

EPIC GEAR - Always The best of the best

I wear nothing but mudgear on the my feet. From the no show socks and 1/4 crew up to the crew height and tall compression socks. I own every flavor in almost every color. They are all I wear, and have been wearing for almost five years. Take it from me - these socks and their race apparel are the best out there. Thank you MUDGEAR!!

Best socks for OCR, trail, running, whatever

I love the mudgear socks. I’ve worn the tall compression, ruck and ankle mudgear socks. I love that they don’t slip down. Ever. And the cushion around my foot is amazing. Even through a pond 3+hour race.

New favorite trail and winter running socks

I keep having mixed experiences with the socks I use for trail runs and winter runs, so I decided to give these Mudgear 5" socks a try. I was immediately impressed. They fit perfectly and keep my toes and ankles warm on cold winter runs. The quality of the toe fabric is better than the other socks I was using and should hold up well over many miles without holes. I am excited to have found these!

Comfort meets functionality meets style

I took the MudGear shorts and socks through the swamp/cow pasture of Florida for the Central Florida Trifecta and they were PERFECT. They were quick drying, comfortable, and held "everything" in place. I wish I bought MudGear sooner. I did not have to focus on my clothes, which made the races more enjoyable.
