Product Detail & Benefits


When we were introduced to Swiftwick's Performance line of compression socks, we were anxious to proudly put the Hammer Nutrition logo on them, expressing our endorsement of this ultra-smart, ultra-comfortable technology.

In addition to offering softer, stronger construction and supreme comfort, Hammer Nutrition compression socks help improve vascular performance and blood flow, reducing leg fatigue and speeding recovery after a long training session or event.

In keeping with Hammer Nutrition's Made in the USA policy, Swiftwick is manufactured in Tennessee, and the company keeps a close eye on the sources of their materials.

Rated 4 out of 5 by from Great socks I bought them a week ago and used them that weekend at a 6 hr race. Tight enough around the ankles mid calves. Only getting 4 stars because I would like them to be a little longer. Great feel.

Rated 2 out of 5 by from Review is for the long compression socks Short version appears to be fine (I only tried them on so far and have not worn them on a bike ride yet). I like the feel and fit of them.  Long version appears to be  not of same quality as other long athlete-oriented compression stockings that I own. They are also a tad too short in length which renders them close to useless for that reason alone. I will be wearing them occasionally and they will be used as back ups. I am only posting this comment because I was asked.
