Proud to be the Official Sock of the Avon 3-Day Walk for Breast Cancer!! Good Luck Participants!! At WRIGHTSOCK we believe in supporting a healthy lifestyle. As part of that belief, we have manufactured our number one product, the Running Sock, with the pink ribbon logo that represents Breast Cancer. We hope that our dedicated users will enjoy the new logo and new users will be enticed to try the product because of the logo. We will donate a portion of our sales of this Ribbon sock to Breast Cancer Research. So enjoy the comfort of the sock while knowing that you are helping support the cause!
