There has been a recent increase in participation in walk-a-thons, marathons and race for life raising awareness and funds for this dreaded disease. The Pink Ribbon sock from WRIGHTSOCKâ„¢ helps by not only raising funds, but also by providing a blister free experience for the people dedicated to finish their walk or run. The design is perfect in any athletic or casual shoe.
