Vital performance for fast-moving endurance athletes. They're thin and airy and made to move moisture away from skin. Felted yarn construction, with a channel weave under the foot and arch, maximizes cushion with minimal weight, advances airflow and dissipates excess heat. Ultrasoft, chlorine-free merino wool cushions the entire foot, nylon adds durability, Coolmax®, polyester and spandex improve wicking performance and aid in stretch recovery. The low-profile fit is cut higher in back for extra Achilles protection. Lintoe® seamless toe construction is a thankful detail at the end of a hot day. Made in USA.

Wonderful Sock. Super Light, sturdy, and blister-proof
Super, super, super socks. Doesn't weigh a thing. Have been in same pair for 3 days and barely any stink. Absolutely not blisters.
Get a pair of these while on sale, so worth it.
Great Sock
Really keep your feet dry. They are thin but very comfortable. I do aerobic exercise every day and these socks have worked well.
Great socks
Amazing socks, very comfortable, and do a great job of keeping my feet dry while jogging or hiking. (Plus very comfortable to wear around the office)
Quality & Comfort
Very comfortable. I have had these for a while now and they are still holding up. I do air dry them. They also look great.
I Like my socks
Good socks tricky to find in the dryer.
Great Running Sock
A nice lightweight sock. Hold their shape well, dry quickly, seem to be holding up well so far.
Great sock
I have been running in the ultra lightweight endurance patagonia sock for the past 5 years. The 30% merino wool, 20% Coolmax fabric provides a more gripping sole and a nifty knitted top for excellent breathability. The articulated nature of the fabric weave provides an outstanding fit. Its certainly the best light weight sock I have found and great with orthotics.
Durable, light, keeps feet dry
What a difference it is to use these instead of pure cotton blend socks. My feet can breathe! Great cushioning at the heel, and good lining at the toe. Would definitely buy again!
Quality sock, keeps feet dry and cool
Excellent synthetic blend sock, doesn't shrink after repeated washings. Solid cushioning at the heel and toe. Unlike pure cotton or wool socks, my feet don't get drenched, nor do I have abrasion problems at the toe or instep. I will buy this style again in the future.
Great all-around sock
I purchased these socks for a hiking trip in hot dusty conditions. They are lightweight, cool, comfortable, and the back of the sock is slightly higher and padded to protect the Achilles tendon. I hiked for 5 hours with no chafing or blisters. The only negative was some slight pilling where my shoes rubbed, otherwise great socks!
