Been looking for the end-all, be-all wool trail sock? We've been getting tons of requests for an ISW Crew, and it's finally here, in a 2pk.

The new ISW is a power-packed running sock built for the trail and beyond. Constructed with Isolwool®, the ISW utilizes merino wool and polypropylene to deliver superior moisture movement. A light cushion prevents blistering and enables prolonged performance in the harshest conditions. Wool naturally fights bacteria allowing the sock to remain clean and fresh. The ISW is designed to perform in hot or cold environments - and to excel on the trail.

They're knitted and currently available in limited quantities. Both Medium and Large now available with Orange highlights. Mediums also available in Limited Edition Pink highlights.

39% Merino Wool, 39% Polypropylene, 20% Nylon, 2% Spandex

Finally good price

The ISO Wool sock is great even in 87 degree weather! I originally bought this sock for the colder wet conditions, and decided to try it out in the heat. I’m amazed by the quality and ability to breathe while providing comfort during exercising! Great sock, I’m hooked and definitely recommend!

great product, as always - Fitsoks are the best!!

Krista C.

Different than what was pictured which was deciding factor to purchase the socks. Didn’t feel like going through the trouble to return them but not really satisfied since they are not what was advertised.

Tricia P.

My husband loves the isowool socks after buying the shorter ones for trail running. He bought these as his every day work socks and loves them. Price, quality, and comfort are all there! He’s tough on socks and these look and feel like they will hold up nicely. And the wool socks don’t get stinky, and don’t hold in smells like a polyester or poly cotton sock does! Thank you Fitsok! Love being able to support businesses in my own state.

I’ve worn these socks for several years now and has to be some of the most durable socks I’ve ever worn! Well worth the money! Highly recommended!

Happy but was Sent the wrong ones. Ordered the green stitch ones. So what’s up. How does that work

The socks are very warm. I would have given five stars, but the part that goes up to my calf is very short, unlike any other crew socks I have.

Love these socks!

Warmer and obviously fit better than Darn Tough socks. Two pair will accompany me when thru hiking this June. The black color will dry faster on the trail. Appear durable, but time will tell if or when a toe pokes through.

Mary F.

Ordered these for my husband and the wrong thing was sent. But they were very helpful in getting things straightened out and now my husband is enjoying his socks. He is very cold natured so these provide him the warmth and dryness he needs during the winter. I will definitely order more from FitSok.

Jesse M.

Have been a long time fan of Fitsoks. These are no exception. Fit great, seem to last forever.

Daniel D.

Love the fit, feel and durability of my FitSoks!!

Adam C.

These are my favorite socks. I have gotten rid of most of the other socks in my sock drawer and replaced them with these. I got my first pair for running but I wore them to work one day and now I wear them to everyday with my work boots. They're good for running too. Best socks I've owned.

Steve W.

Perfect socks. Wicks away moisture.
