ISW Isolwool No-Show (3 Pair Pack) Runner Socks

Regular price $25.00

Stay warm and dry with our ISW Wool No Show Athletic Sock, available in a pack of three! Most people don’t associate wool with running, but those people probably don’t know about Merino Wool. We know you’ll be impressed with the awesome features these socks have, but we also think you’ll love the subtle design as well. Black is a great color if you don’t want to draw a lot of attention. After all, it’s important to stay focused on your run!

No one likes the feeling of hot, sweaty feet, especially when you’re trying to avoid distractions. That’s why we designed the ISW Wool No Show Athletic Sock from ISW Wool. ISW Wool wicks moisture away from the foot by using mesh venting and Flowtek channels, keeping your feet cool and dry no matter how long your run lasts or how far you have to go! Additionally, ISW Wool features an incredible amount of arch support, which ensures that your socks have the proper fit and won’t slide around inside your shoe.

The light cushion on the bottom of the ISW Wool No Show Athletic Sock prevents blisters and extends performance, even in the harshest conditions!

We make every pair of socks in our North Carolina factory, which means that all of our socks are USA-made! The two brothers behind FitSok are passionate runners who happen to be third-generation sock makers. They’ve worked hard to engineer socks from the highest quality materials because they knew that athletic socks could be better. Since these products are so affordable, make sure you stock up on a few of your favorite styles and designs so that you have a fresh pair of running socks ready for you whenever it’s time for another run. Love what you see? Want 40% off your first purchase? Be sure to sign up for our email list, and you’ll get exclusive offers and deals on all of our products! We love what we do, and we can’t wait to see all the milestones you reach with our ISW Wool No Show Athletic Sock.

For a limited time, we're offering the CF2 Crew with Shadow Yarn TwistDye fabric.

At the core of this sock is Shadow Yarn - our durable, super-soft fabric that made our CF2 a best seller. By taking threads of Gunmetal and Black fabric and twisting them together, we've created a unique and one-of-a-kind look.

Whether wearing on a cold evening or down a brush-filled trail, the CF2 Crew is versatile and takes a beating. It excels in cooler weather, as the Twistdye retains warmth better while wicking away moisture.

Some sock-nerd tech talk:

Utilizing Flowtek™ channels, the CF2 transports moisture and heat from areas of highest to lowest concentration for a comfortable, thermally balanced sock.

The CF2 is engineered with Max Arch support and mesh venting for excellent fit and function. Every pair has a cushioned footbed to enhance comfort and extend athletic performance of the foot.

2 pair come in each pack, to keep you up and running.

These Limited Edition Skully Wool Running Socks are built with performance features to provide the wearer with superior comfort and fit. Just a few of these features include mesh venting and Flowtek channels, which move moisture and heat away from the wearer's foot even while the Max Arch support keeps the socks snug against the feet.

The Skully Wool Running Socks are constructed from Merino wool. Merino wool is one of the most popular and sought-after materials for socks due to its fantastic moisture-wicking properties. This wool absorbs water and then dries it exceptionally fast, which keeps moisture off your feet more efficiently and effectively than any other sock fiber. Merino wool is especially more efficient than cotton, which absorbs sweat but doesn't move it away from the foot.

Moisture isn't the only thing these Skully Wool Running Socks absorb; they also get rid of foot odor since bacteria that feed on moisture aren't able to live on moisture-less feet. No bacteria = no smelly feet, simple as that!

Arguably, the most important feature of the Skully Wool Running Socks is how lightweight and super-soft they feel against the skin. Merino wool doesn't cause the same itchiness that other wool does, which means that you'll stay surprisingly comfortable through your entire run. Run longer and faster when you run with our wool running socks, featuring a fun design that all of your runner buddies will be jealous of!

If you're ready to take your run to the next level, these socks are for you. Not only do they come with all of the amazing features we mentioned above, but they're also backed by a lifetime guarantee, which means you can say goodbye to your stringy, worn-down, old collection of socks with just the click of a button! Double-check the sock's size chart before ordering to ensure the most perfect fit possible.

Do you need some guidance in the buying process or have any questions about our Skully Wool Running Socks? No problem! Reach out to our customer service team. We've created limited quantities of these socks, so get yours quick!

ISW Isolwool No-Show (3 Pair Pack) Runner Socks

Regular price $25.00

Stay warm and dry with our ISW Wool No Show Athletic Sock, available in a pack of three! Most people don’t associate wool with running, but those people probably don’t know about Merino Wool. We know you’ll be impressed with the awesome features these socks have, but we also think you’ll love the subtle design as well. Black is a great color if you don’t want to draw a lot of attention. After all, it’s important to stay focused on your run!

No one likes the feeling of hot, sweaty feet, especially when you’re trying to avoid distractions. That’s why we designed the ISW Wool No Show Athletic Sock from ISW Wool. ISW Wool wicks moisture away from the foot by using mesh venting and Flowtek channels, keeping your feet cool and dry no matter how long your run lasts or how far you have to go! Additionally, ISW Wool features an incredible amount of arch support, which ensures that your socks have the proper fit and won’t slide around inside your shoe.

The light cushion on the bottom of the ISW Wool No Show Athletic Sock prevents blisters and extends performance, even in the harshest conditions!

We make every pair of socks in our North Carolina factory, which means that all of our socks are USA-made! The two brothers behind FitSok are passionate runners who happen to be third-generation sock makers. They’ve worked hard to engineer socks from the highest quality materials because they knew that athletic socks could be better. Since these products are so affordable, make sure you stock up on a few of your favorite styles and designs so that you have a fresh pair of running socks ready for you whenever it’s time for another run.
