Fantastic Sock
Review by Huntley, Scott on Mar 20, 2013
I've been using the PERFORMANCE Four for about 3 months now. I can't imagine buying another brand of sock every again (unless SW stops making them - and then there will be BIG trouble). Great fit, just the right amount of compression, light weight, breathable (which is important for my here in Florida).

Glad my friend Craig Evans turned me onto this great product!

I don't ever want to take them off.
Review by Mclaughlin, Alex on Jan 26, 2013
Great socks. Worth every penny. Everyone who participates in endurance sports knows that comfort is a pretty big deal and these definitely don't shy away from the task when it comes to 3-4 training sessions. These socks have been with me for several months now and they still fit like the first time I wore them.

Great Socks
Review by jacoby, alan on Oct 16, 2012
I have been wearing the same pair of Swiftwick 4 PERFORMANCE compression socks to every race this season. I race 24 hour solo mountain bike events, and have ridden over 1,000 miles on these socks so far. They've been muddied, beaten, and washed countless times. They still fit great, barely any signs of wear, and most importantly still feel amazing. I'm sold for life.

Got to have them...
  Review by Lambert, Brian (North Carolina USA) on Sep 24, 2012
I had major issues finding a sock for my marathons and triathlons that met all my performance needs. I came across Swiftwicks and I haven't used another sock since. Its really crucial to have a sock that keeps your feet healthy during high endurance races, and the Swiftwick's dominate the industry standard.

4 Hr Run from the Cops
  Review by Morgan, Jeremy (North Carolina USA) on Jul 16, 2012
The reviewer has last purchased this item on Feb 07, 2012
I have been wearing Swiftwicks for almost a year and love every pair I own. I even got my wife turned onto wearing them to the gym. I wore these this past weekend for the 4 hr MTB race Run from the Cops held in Greensboro, NC. It was low 80's at the start and by the end around 1pm it had gotten to 96 with heat index of 103. After all the water I poured on me that ran into my shoes and 4 hrs of sweating they had not stretched or moved on my feet. Feet felt great and I never ride the single speed or road bike without them. No other socks get worn for any activity that I do.
