Fox Racing Proforma KB Socks 5 5 1 1
They've been great during long rides in 90+ degree heat I wear these socks on long road rides under my jeans and they are outstanding at fighting fatigue. They are knee brace socks, but I wear them for the compression all the way up to my thighs without braces. I'm 6ft tall and weigh 180lbs with size 11.5/12 feet in U.S. sizing and the large size in these socks was perfect. The sock could easily stretch to accommodate a 13. The socks come close to hitting my groin when stretched all the way up. I had a pair that I recently wore on a 300 mile trip and I decided to come to Revzilla to get 3 additional pairs for a 700 mile trip I have planned soon. They've been great in 90+ degree heat in Texas. They kept my legs cool through the ride and I noticed a lot less fatigue at the end of the ride. August 23, 2015

RevZilla Store asked: Why did you choose this?
Jose Luis D: I recently started wearing a pair I had forgotten I had purchased years ago. I loved the socks for compression purposes on long road rides so I had to get more for an upcoming trip. Aug 23, 2015
