Excellent sock for all day
Review by Christa , Texas on May 17, 2016
I wear this sock all day every day except when I must look less sportif. I love the lightweight expandable easy to wash and dry material. The sock is great for all day compression. Mornings it is easy to get on, evenings let me know that the sock has kept my circulation flowing, especially of the lymph system. Wonderful product! Been wearing this 4 inch cuff now for 9 years.
Thanks!

Great socks!
Review by lucas Smallidge on Sep 07, 2013
Best and most comfortable socks I have ever worn, ordered a pair then bought 5 more. Greatest socks ever! I have been wearing them for weeks and no signs of wear. They breathe great and the compression is really comfy!

PERFORMANCE FOUR, the ULTIMATE sock!
Review by Jonathan Copsey on Jul 28, 2013
This sock is my sock of choice when both competing and practicing. I've ridden these socks to 5 National Paralympic Road Championship titles, and uncountable trips to the grocery store. Whether I'm out riding the roads or even relaxing at home, the PERFORMANCE FOUR is the best fitting, most comfortable, and highest quality sock I've ever worn. I even wore them to a wedding one time and was scolded by my date for not wearing dress socks. Obviously, she didn't understand how amazing these socks are!

My new long course sock
  Review by Christopher Stock (Virginia USA) on Jun 05, 2013
The reviewer has last purchased this item on Sep 16, 2013
I had been using these socks for cycling during cooling rides for the past several years which worked great. Recently moved up to Ironman distance racing and decided to give them a whirl on my long runs to provide some extra support. I was immediately hooked on these for running now as well and will be my go to race socks for 70.3 and Ironman distance racing. Support comfortable and extra compression support in the ankles to help hold everything together.
